Bucket dredging to mine and extract gold and tin from rivers is a global industry that has had a range of negative effects on physical environments. These include the destruction of riparian soil profiles and structures, artificial channel straightening and loss of in-stream biodiversity. In this paper we evaluate the immediate effects and long-term consequences of bucket dredging on rivers in Victoria and New South Wales during the period 1900–1950. High quality historical sources on dredge mining are integrated with geospatial datasets, aerial imagery and geomorphological data to analyse the scale of the dredging industry, evidence for disturbance to river channels and floodplains and current land use in dredged areas. The study demonstrates that the environmental impact of dredging was altered but not reduced by anti-pollution regulations intended to control dredging. An assessment of river condition 70–100 years after dredge mining ceased indicates that floodplains and river channels continue to show the effects of dredging, including bank erosion, sediment slugs, compromised habitat and reduced agricultural productivity. These findings have significant implications for river and floodplain management. [ABSTRACT FROM AUTHOR]

This paper examines the redevelopment of the site of Sydney’s 2000 summer Olympics, locating it within debates over the legacy of these events. The paper describes some of the key stakeholders involved in the redevelopment and planning of the site. It provides an overview of the regulatory context and governance bodies that have structured the space since the staging of the Olympics, then identifies two key areas of private-sector involvement, in event space and in business development, where tensions emerged over how the site should best be governed.

Many suburban areas in Australian cities built between the 1930s and 1960s are facing major challenges from socio-demographic change, ageing housing, long-term disinvestment and entrenched pockets of social disadvantage. Yet despite emerging relative disadvantages, these middle ring or ‘third city’ suburbs are experiencing locally generated piecemeal market-led reinvestment and renewal. This paper explores housing, household and housing investment characteristics and trends in the older parts of Sydney’s western suburbs drawing on analyses of socio-demographic and development application data. Policy options to achieve more appropriate urban renewal outcomes under broad social sustainability criteria are canvassed. Similarities and differences to the American ‘first suburb’ phenomenon are noted. [ABSTRACT FROM PUBLISHER]

This paper interprets macroscopic charcoal (>250 μm), humification and loss-on-ignition over the last ∼14 200 cal. BP from Goochs Swamp, located to the west of Sydney in the Greater Blue Mountains World Heritage Area. This study aimed to investigate relationships between humans, climate and fire through time, primarily by comparison of these palaeoenvironmental indices with archaeological evidence from the region. Climatic forcing can explain all periods of change in the history of fire at Goochs Swamp: fire activity was variable during the Lateglacial-Holocene transition, low during the relatively stable climate of the early Holocene, and high but variable after the onset of modern El Niño from the mid Holocene. Although the dominant control on fire in this environment during the Holocene appears to be climate, fluctuations in the late Holocene may reflect anthropogenic fire or human responses to climate change. The archaeological record of the Blue Mountains and other parts of the Sydney Basin illustrates that Aboriginal people altered subsistence, resource and land-use patterns in the late Holocene. We propose that these cultural measures were adopted to overcome new risks as the frequency of ENSO events increased, and the natural fire regime and resource reliability changed. These strategies perhaps included a more systematic use of fire. The most parsimonious interpretation of the evidence for changes in fire activity at Goochs Swamp in the light of nearby archaeological evidence is that Aboriginal people used fire within a changing climatic framework.
