change. This includes increasing use of stormwater and sewage recycling and managed aquifer recharge . All major coastal Australian cities have desalination plants. Household scale adaptation, like rainwater harvesting, water-smart gardens, dual flush toilets, water-efficient showerheads and voluntary residential use targets, can help reduce water demand by up to 40% . Water utilities across Australia have established climate change adaptation guidelines . Coordinated efforts to reduce demand, design and retrofit infrastructure to reduce flood risk and harvest water and to practice water-sensitive urban design are evident . Transitioning centralised water systems to a more sustainable basis represents adaptation progress but is complex and faces many
