Sydney must plan entire cities to beat extreme heat, study finds
Sydney's Greater Sydney Heat Taskforce released a 40-recommendation plan to help residents prepare for worsening heatwaves.
Western Sydney is sometimes the hottest place on Earth, yet many people cannot simply stay cool. Not everyone can run an air conditioner.
Not everyone has a well-insulated home. Not everyone has close neighbours to check on them.
A new study examined how one city bridges these gaps. The Greater Sydney Heat Taskforce brought together 373 representatives from government, health, emergency services and community organisations over 18 months.
They created the Greater Sydney Heat Smart City Plan, launched in December 2024. The plan sets 40 recommendations for 2025 to 2030, covering awareness, cooler homes, neighbourhood design and protecting vulnerable people.
Unlike floods or bushfires, extreme heat has historically fallen between different government departments, leaving responses fragmented. The plan succeeded by building trust, clarifying who does what, and identifying governance gaps.
Success now depends on long-term funding and institutions staying committed.

Why it mattersAs Australia's summers grow hotter, coordinated city-wide heat planning saves lives, especially for elderly people, pregnant women and those with existing health conditions.
AustraliaSydney's 5.6 million residents will benefit directly. The plan could set a model for heat preparedness across Australia's other major cities as climate change intensifies.
