Water management increasingly focuses on tackling stormwater pollution to improve waterway health. Community members have a role in adopting pollution-reduction practices and supporting technologies such as water sensitive urban design. However, because communities are unfamiliar with these practices and technologies, little is known about how they make sense of these 'water sensitive innovations'. Drawing on Diffusion of Innovations theory, we conduct focus groups across different regions of Australia. Our findings indicate that key barriers to adoption included poor understanding of the relative advantage of these practices and technologies, and perceived poor compatibility with community members' lifestyle and local geography. In turn, appraisals of relative advantage were constrained by limited observability of stormwater pollution and the benefits that innovations generate for people and the environment. Our findings suggest engagement strategies should emphasize the relevance and advantages of water sensitive innovations, and help individuals visualize the intangible elements of stormwater pollution management.

Climate change is the most significant threat to the Great Barrier Reef (GBR). While Australians express appreciation and concern for the GBR, it is not clear whether they connect climate‐related action with reef conservation. An online survey of 4,285 Australians asked "...what types of actions could people like you do that would be helpful for the GBR?" Only 4.1% mentioned a specific action related to mitigating climate change; another 3.8% mentioned climate change but no specific action. The most common responses related to reducing plastic pollution (25.6%). These findings demonstrate that most Australians have poor capacity to identify individual climate‐related actions as helpful for reef protection, and that generic calls to action—such as "protect the reef"—are unlikely to elicit climate‐related actions. As such, reef conservation initiatives must explicitly promote actions—in the home and in society—that reduce emissions and support the transition to a low carbon society. [ABSTRACT FROM AUTHOR]
