This paper explores the hydrological history of the Hunter River and Estuary (Newcastle, Australia), to identify pathways for incorporating climate-sensitive adaptation approaches into urban development and planning. The research method utilises mapping as a methodological discovery tools to visually articulate the correlation of pre-colonial hydrological landscapes, the transformation of the estuary over two centuries, the areas identified as at risk, and the opportunities for developing a climate-resilient estuary. This research aims to contribute to the redefinition of the discourse on the role of estuary planning for changing climate, focusing on four critical aspects: identify the impacts of urbanisation and industrialisation on ecosystems and its correlation with climate hazard at the estuary; visualise such transformations over time and space to identify critical spatial and climate factors threatening inhabitation; propose strategic spatial practices towards adaptation and resilience; and synthesising the options to foster reflective thinking and establish a correlation with novel policies, governance and practices. The study highlights that adopting new urbanism aligned with cultural and ecological principles can mitigate future climate impacts through re-naturalisation and urban adaptation to sea-level rise by focusing on proactive approaches to building resilient communities. This paper also acknowledges the need for site-specific adaptive design and planning strategies at multiple scales and governance levels. [ABSTRACT FROM AUTHOR]

Accurate land valuation is necessary for tax purposes, land resources allocation, real estate management and urban development and planning. Since various factors from different domains affect land prices through non-linear relationships, automating the land valuation process on a large scale is a complex task. Advanced technologies in big data analysis and artificial intelligence have demonstrated superior capabilities in knowledge extraction in such cases. Accordingly, this paper develops and compares the performance of four Automated Valuation Models (AVMs) based on machine learning and deep learning techniques utilizing physical, geographical, socio-economic, environmental, legal and planning factors in Melbourne Metropolitan, Australia. According to the results, the eXtreme Gradient Boosting (XGBoost) method outperforms other algorithms of Support Vector Regression (SVR), random forest and Deep Neural Network (DNN). This method has achieved the coefficient of determination (R2) of 0.862, Mean Absolute Percentage Error (MAPE) of 0.139, and normalized Root Mean Square Error (nRMSE) of 0.281. The achieved high accuracy is due to incorporating a wide range of driving factors and applying innovative feature selection and hyperparameter tuning procedures evaluating various possible feature sets and hyperparameters. Accordingly, this paper can contribute to research, governmental and industry-based activities in terms of developing AVMs for mass land valuation. • Automated land valuation models using machine learning and deep learning • Comprehensive feature set and hybrid feature selection process for robust model performance • Spatial mapping of land values in large urban areas • Contribution to fair housing policies and urban development by accurate land valuation • Practical insights for housing affordability strategies in terms of land management [ABSTRACT FROM AUTHOR]

The aim of this paper is to investigate the empirical correlations between inter-city population distribution, intra-city urban economic structures, and networked inter-city relationships to propose a conceptual classification framework for the Australian urban system. This paper sets the pre-COVID-19 benchmark for future research which will investigate the impact of COVID-19 on the economic geography of the Australian urban system. This research confirms that the form of Australia's urban structure is informed by a combination of population distribution, economic concentration, specialisation and diversity of industries and occupations, and networks between cities. Based on these results, we propose an urban structure framework characterised by hierarchical sub-systems and typologies of cities. The framework consists of standalone regional centres and larger cities which form a networked megaregion. Additionally, we propose five typologies of cities based on their functional roles. The Australian urban system presents a unique hybrid economic geography where its structure of networked megaregions of cities and standalone regional centres each with its complementary functional roles, presents itself an interesting case study to inform population policies for other geographies. • This study proposes a method to synthesise city size, economic structure and their networked relationships. • Principles of economic agglomeration mostly apply within the Australian context however, there are nuances and exceptions. • Proximity has a role to play when determining the economic roles of cities and the strength of interactions between cities. • Two urban sub-systems exist in Australia: standalone regional centres and megaregions. • Five city types in Australia which considers their size, economic structure and geography.

Abstract Household decisions to move from or stay at a current location may be based on a great number of variables. There has been substantial discussion among planners about the effect of the built environment in the choice of residential location. However, there is limited research on the role of non-motorised accessibility on residential location. Households may base their decision to move from or stay at a current location on the neighbourhood's accessibility. The public transport accessibility, walkability and bikeability of a neighbourhood may affect residents' decisions to stay or move from their current location. The focus of this paper is on modelling and comparing the influence of non-motorised accessibility measures on the number of years that households stay at their current location. The paper addresses this issue by employing three non-motorised accessibility measures in separate ordered logistic regression (OLR) models. Focusing on metropolitan Melbourne, Australia, the Victorian Integrated Survey of Travel and Activity (VISTA, 2012) was adopted to model years of residency incorporating socio-economic characteristics, built environment features and accessibility measures. Key findings indicate that non-motorised accessibility has statistically-significant impacts on the number of years that residents live at their current address. Furthermore, of the accessibility measures, access to public transport has the greatest impact. Highlights • This paper aims at investigating the influence of non-motorised accessibility on residential location. • Focusing on Melbourne, Australia, three accessibility measures were employed in Ordered Logistic Regression (OLR) models. • Findings indicate that accessibility had significant impacts on residents' tendency to stay in the same neighbourhood.

Public spaces are the loci of complex interactions among multiple stakeholders whose decisions and activities affect places' qualities. The paper builds upon governance theory to provide a holistic in-depth approach in understanding the complexity and quality of the place-shaping processes in public spaces. In the absence of adequate conception of governance in urban design and public spaces, the paper introduces a framework for analysing governance capacity of public spaces and applies the framework to a flagship but highly contested public space in Brisbane, Australia namely South Bank Parklands. The proposed framework encompasses four major components of 1) actors and stakeholders, 2) governance structure, 3) governing tools, and 4) governing tasks. The framework puts special emphasis on the contextual factors, the way public spaces are shaped and governed, and political economy of the space. The case study application showcases the applicability of the PSGF which helps holistically analyse the trends in public space governance structure accounting for the diversity and complexity of all elements involved. The findings reveal that South Bank Parklands governance is mix-structured, hierarchical, and highly political. It is, however, a likeable public space for which civic engagement in the decision-making processes is notably limited. [ABSTRACT FROM AUTHOR]

In this paper we interrogate how digital technologies and practices contribute to imaginaries of counter cities by telling the stories of people who navigate digital inequality. Digital inequality offers a lens onto the ways in which the privatised provision of services reshapes opportunities for collective organising. Digital technologies are commonly viewed as useful tools for collective organising, overlooking the fact that digital products are inequitable in their functioning and availability. In Australia, internet connections are offered as a for-profit service and digital inequality is persistent. The paper presents focus groups and participatory mapping interviews with residents of a Melbourne public housing estate. The study reveals that public housing residents pay relatively more money and receive lower quality service from internet providers. We identify three forms of dependency that arise as residents endeavour to stay connected to an essential infrastructure that was designed without their needs in mind: strategic alliances with community organisations to secure a digitally connected future; household strategies for meeting digital needs; and collaborative troubleshooting with technological 'experts'. In the conclusion we stress that digital infrastructures both require and enable collective organising and we argue that the political projects of counter cities must protect those infrastructures that support the relationships that can lead to more equitable cities. • Public housing residents pay more for internet and receive less reliable connections. • Telecom providers do not communicate barriers nor provide solutions within their ability. • Individualisation of services inhibits collective action for just provision. • Concept of counter publics needs to be critical of inequitable internet provisions.

Rapid urbanisation is impacting availability of greenspace, regarded as a cornerstone of liveability in cities across the globe, presenting challenges for residents and governments alike. Scholars from fields as diverse as planning, engineering, health and psychology, are calling for more urban greenspace to remedy manifold urban challenges (e.g. stormwater attenuation, pollution reduction, health promotion and temperature modulation). Yet few have paused to question the viability of urban greenspace provision, especially its financial and administrative burdens for local government, nor whether simply providing more greenspace is efficacious. This paper investigates the perspectives of elected officials and local government officers towards greenspace provision in a rapidly growing Australian city: Logan, Queensland. Employing an in-depth case study including semi-structured interviews, public documents, and municipal and census data, the paper elucidates key factors that affect provision, highlighting the tension between supply and demand, and the role of planning practices. In determining greenspace provision, three clusters of factors are particularly instructive: (i) community expectations; (ii) governance tools; and (iii) financial resources. The findings point to a critical issue: providing urban greenspace cannot be simply reduced to a matter of inadequate resources - community expectations are a pivotal and often over-looked factor shaping urban greenspace provision. [Display omitted] • The clamour for more greenspace could be setting local governments up for some serious future policy deficiencies • Providing urban greenspace is more than supplying land and revenue for facility development • Resourcing gaps arise when attempting to use existing resources optimally to achieve corporate objectives • An effective approach to urban greenspace planning must adequately respond to the gaps in expectations and resources [ABSTRACT FROM AUTHOR]

Stormwater has been acknowledged as a major concern in cities because of mismanagement of this resource. It has also been underestimated as a resource in climate change actions and policies. Water sensitive urban design (WSUD) is considered as an effective adaptation measure to address these issues while providing many co-benefits. This paper reports the challenges of implementing WSUD in the Australian context. Semi-structured interviews were conducted with 57 experts in Australia. The experts are involved in design, research, engineering, and planning policy in both public and private sectors. The qualitative analysis of the interviews involved thematic and content analysis through NVivo12. Analysis of the responses indicated six main challenges including financial, innovation and evaluation tools, capacity, institutional arrangements, and policy. The experts believe that a lack of standardized design and implementation can be addressed through collaborative design processes. They suggest a robust structure of approval process and establishing clarity of roles and responsibilities in all sectors. All respondents confirm the critical role of monitoring and maintenance in these projects. It is suggested that allocating recurrent funding for these ongoing activities from the beginning and setting incentives to engage communities and local councils in maintaining the projects can be helpful. • Provides insights in investigating the impact of social and organisational structure towards achieving WSCs. • Conducted qualitative analysis of interviews and survey questions. • Recommendations to advance stormwater management planning and design.

Rapid urban population growth promotes the outward expansion of cities and strengthens demand for outer metropolitan infrastructure. In a practical sense, creating sustainable greenfield communities is problematic given the expensive, multidimensional nature of infrastructure. Inwardly-looking metropolitan imaginaries can result. Although urban political economy perspectives acknowledge variability in local public-private sector relations, thereby raising the prospect of developer obligations, the latter are not without limited. To further strengthen understanding of sub-national government capacities and outer metropolitan infrastructure policy, additional institutionalist interpretations are necessary. Alongside or in between the limits of developer contributions and ad hoc public funding streams, this paper confirms the importance of extended policy perspectives by identifying and evaluating three state level policy responses on the outskirts of Melbourne, Australia: spatially designated funding, public private partnerships (PPPs) and community infrastructure brokers. • Large scale expansion on Melbourne's edge, plus multidimensional infrastructure deficits as identified by council officers • The importance of institutionally sensitive urban political economy perspectives for interpreting infrastructure deficits • The importance of investigating outer metropolitan policy dynamics beyond developer contributions • Three emerging policies: spatially designated funding, public private partnerships and infrastructure community brokers • The need to further investigate sub-national local–state government relations given partial responses [ABSTRACT FROM AUTHOR]

Large-scale administrative data collected by municipal government are increasingly being used by researchers to better understand a host of urban phenomena and the way they are patterned over space and time. In this paper, council data are used to explore the incidence of complaints about neighbours across urban neighbourhoods using a GIS-based spatial approach. Through an exploratory and a confirmatory factor analysis of the spatially extracted neighbour complaints data, we identify four types of neighbour complaints – animal related; building construction; property management issues; and health and visual amenity issues – that categorise neighbour problems. GIS technologies are applied to map the spatial distribution of each complaint type across the 218 suburbs, resulting in distinct patterns of neighbour complaints in Brisbane suburbs. Our research demonstrates the utility of naturally occurring administrative data as a means of learning more about the social life of urban areas. • We demonstrated the use of a large-scale administrative data to explore neighbour complaints across urban neighbourhoods • We identified four types of neighbour complaints using an exploratory and a confirmatory factor analysis • GIS techniques were applied to map the distinct patterns of neighbour complaints across the 218 Brisbane suburbs • Our analysis provided deeper insights to the nature and spatial patterns of neighbour complaints in Australia's urban space [ABSTRACT FROM AUTHOR]

A recent explosion of research on the travel behaviour of the millennial generation has found that compared to past generations they are taking longer to get a driving license, driving less, owning fewer cars and using transit more. Yet these findings are not universal with some countries seeing increases in driver licensing, little change in driving or reductions in public transport use. Most past research has explored wider social and economic explanations for these trends, such as income constraints and delays in adult life transitions. Very few studies have examined the role that local context plays in explaining the change (or the lack of change) in millennial travel behaviour. This paper aims to compare how trends in young adult travel behaviour differ across diverse city contexts. It uses a comparative descriptive analysis of household travel surveys from cities in three countries (UK, USA and Australia), focussing on auto-miles and transit-miles travelled. We find that each city experienced markedly different trends in young adult travel behaviour that are unlikely to be explained by economic differences alone. We suggest that changes to the transport systems in these cities are likely to be playing an under-recognised role in shaping travel behaviour. We suggest that further research should pay greater attention to the role of the transport system in supporting changes to travel behaviour among the next generation of young adults. • Explores travel behaviour of millennials in 6 areas of the UK, USA and Australia • Macroeconomic trends impact car use among millennials. • Some evidence life stage is impacting travel of millennials. • City investments in transit likely play an important role in these trends.

The federal government of Australia seeks to determine the selection and forms of financing of infrastructure projects in cities, and to prescribe how cities are planned and managed. This role is rationalised through reference to the UK City Deals model and is made possible by vertical fiscal imbalance (the tax revenue it raises considerably exceeds its expenditure responsibilities). Referring to the Constitution, this role is assigned to state governments that are responsible for planning, infrastructure investment and service delivery in the cities. The cities themselves comprise multiple local governments that are ‘creatures’ of state government legislation. State government metropolitan strategic plans and projects inevitably serve the interests of the constituencies needed to win the next state elections. There is no recognition of a metropolitan constituency. Documenting the economic and social disadvantages arising from Australia's form of metropolitan governance, and providing an example for expensive infrastructure mishaps arising from federal and state governments prioritising different transport modes and projects, the paper argues for the creation of representative, accountable and fiscally autonomous metropolitan governments.

'Care' is a keyword for cities and citizens in the 21st century. This paper draws on Emma Power's (2019) notion of 'caring-with' as an ethical and analytical guide for caring action and relational community capacity-building around gambling at the local scale. The focus of analysis is the approval of electronic gaming machines or EGMs colloquially known as 'the Pokies', with particular reference to the Australian context and the experience of Castlemaine - a small town in the south-eastern state of Victoria whose citizens successfully appealed an application for further gambling development. The paper highlights how caring-with re-frames community responses to gambling as an assemblage of localized care practices and relations. This includes, but is not limited to, working to develop a culture of care, challenging systemic injustices, and proactive rather than reactive practices of collective care. • Increasing calls for a care praxis 'caring-with' emphasize the responsibility of a sharing democracy in an unequal world • Caring-with reframes community responses to gambling as social and political, rather than individual and private • This involves the formation of coalitions of strategy, resistance and advocacy for transformative change. • The case study highlights participation and inclusion; transparency and consistency and fairness as key care concepts. • The case also shines a light on gambling in cities and the relational role of communities that seek to resist new development [ABSTRACT FROM AUTHOR]

Conventional housing price prediction methods rarely consider the spatiotemporal non-stationary problem in a large data volumes. In this study, four machine learning (ML) models are used to explore the impacts of various features – i.e., property attributes and neighborhood quality - on housing price variations at different geographical scales. Using a 32-year (1984–2016) housing price dataset of Metropolitan Adelaide, Australia, this research relies on 428,000 sale transaction records and 38 explanatory variables. It is shown that non-linear tree-based models, such as Decision Tree, have perform better than linear models. In addition, ensemble machine learning techniques, such as Gradient-Boosting and Random Forest, are better at predicting future housing prices. A spatiotemporal lag (ST-lag) variable was added to improve the prediction accuracy of the models. The study demonstrates that ST-lag (or similar spatio-temporal indicator) can be a useful moderator of spatio-temporal effects in ML applications. This paper will serve as a catalyst for future research into the dynamics of the Australian property market, utilizing the benefits of cutting-edge technologies to develop models for business and property valuation at various geographical levels. • Spatio-temporal non-stationary is significant in explanation of the variations in housing price; • A proposed spatiotemporal lag is incorporated to increase the accuracy of the models; • Non-linear tree-based models have better performance than the linear model. • Ensemble ML techniques are powerful methods to produce better predictive performance.

Cities must transform in order to address the challenge of climate change and to achieve societal ambitions such as the sustainable development goals. However, a key impediment to achieving transformation is underdeveloped understandings of how key actors and sectors within the built environment work together to achieve goals. This paper addresses these gaps by developing and visually presenting a process map to describe: the key processes involved in producing the built environment across its life stages; key sectors of the built environment, their key actors, and the activities coordinated between them. The process map was peer reviewed by an expert reference group of built environment professionals active in Australia and the UK. The motivation for developing this process map is to facilitate future research to identify and expedite opportunities for coordinated action to address significant societal challenges such as climate change action, and the sustainable development goals – which require transformative action in cities. • Cities must transform to address climate change • We develop a process map to describe the production of the built environment • Process map describes fundamental activities for producing the built environment • Process map spans built environment life stages; identifying activities and interactions of key sectors and actors • Can be applied to inform transformative action targeted at challenges such as climate change [ABSTRACT FROM AUTHOR]

Urbanisation continuously imposes pressure on coastal brownfield sites. At the same time, climate change and associated consequences on coastal environments make these sites less secure for human habitation. Converging stresses make the renewal process of these sites challenging, to the extent that they are often perceived as wicked problems. Several scholars suggest that temporary best solutions are identifiable to address wicked problems via an Adaptive , Participatory and Transdisciplinary (APT) approach. This paper operationalises the APT framework by evaluating the development of a strategic land-use framework for the transformation of a coastal brownfield site in southern Victoria, Australia. Policy and planning documents and in-depth interviews conducted with key stakeholders were analysed. Results show that the process incorporated elements of the APT approach by engaging with diverse stakeholder views during consultation and included community appraisal of alternative scenarios. However, the process fell short of being truly transdisciplinary or collaborative as it separated disciplinary inputs in decision-making. As a result, it did not appear to influence the final plan to achieve adaptive and responsive outcomes. We conclude that a uniquely placed-based and adaptive response can be created when all stakeholders deeply and effectively collaborate to develop shared understandings of the problem and co-create shared responses. We demonstrate that an integrated APT framework, one that focuses on synergies between A, P and T, can provide a useful tool for assessing the decision-making process of complex projects. Furthermore, our recommendations to advance APT can help directing future decision-making processes in similar projects with wicked problems. Unlabelled Image • Coastal brownfield transformations pose wicked challenges to decision makers. • An analytical framework for operationalising the Adaptive, Participatory, and Transdisciplinary (APT) approach was developed. • The APT framework was tested to evaluate a coastal brownfield transformation in Australia. • Suggestions were made for an integrated APT decision making approach. • For a uniquely placed-based and adaptive response, stakeholders should deeply collaborate to co-create shared responses.

In Australia and many other countries of the Global North, public housing estates are being dismantled and redeveloped to create mixed-income communities. Proponents of redevelopment argue that the introduction of private housing will reduce public housing residents' experiences of stigma. In this paper, we interrogate these assumptions by identifying the degree of stigma directed at the social housing system, the characteristics of those most likely to stigmatise, the impact of proximity to public housing estates on stigmatisation and the words used to describe social housing. Our empirical strategy relies on a multi-dimensional social housing stigma scale, cross-sectional ordinary-least-square regression analysis and a qualitative analysis of respondents' association with the term public housing. We find that a higher level of stigma is correlated with private residents, older respondents, lower incomes and those that have lived in their current neighbourhoods for longer. Drawing on social contact theory, we investigate contact with public housing residents as a predictor of stigmatisation. We find that intra-group contact, positive interactions between social and private residents and proximity to Kensington Estate, a mixed-tenure development, contribute to lower stigmatisation. • Contact with social housing tenants per se is not associated with reduced stigma. • Positive interactions with social housing residents reduce stigmatisation. • Social housing stigma decreases with proximity to a mixed-tenure development. • Individual characteristics influence stigma towards social housing residents. • Support for social diversity is more impactful than proximity to public housing estates.
