Australia's extreme heat as deadliest natural disaster needs urgent policy action
Consensus Summary
A report by the NSW Net Zero Commission reveals extreme heat has killed more Australians than all other natural hazards combined between 2000 and 2018, with Western Sydney hardest hit. The commission urges reforms including updated planning laws, thermal-safety standards for housing, and emergency response plans similar to bushfires and floods. Vulnerable groupsâelderly, disabled, and low-income rentersâface disproportionate risks, with many lacking cooling options or support. The Bureau of Meteorology warns of worsening conditions due to an upcoming El Niño. While the NSW government has taken some steps, such as $45 million in greening projects and insulation upgrades, advocates argue more action is needed to prevent future deaths. The reportâs recommendations hinge on stronger policy alignment, transparent data reporting, and sustained attention to heat risks as climate change intensifies.

Key details reported by multiple sources:
- Extreme heat caused more deaths in Australia between 2000â2018 than all other natural hazards combined (over 18 years).
- The NSW Net Zero Commission called for updated planning rules and emergency responses to address extreme heat, comparing it to bushfire and flood preparedness.
- Western Sydney was identified as a hotspot for heat-related fatalities in the 2000â2018 period.
- The report recommends minimum thermal-safety standards for rental, social, and Aboriginal housing, which would improve 35% of NSWâs housing stock.
- NSW Health was urged to track and publish data on heat-related deaths, and SafeWork NSW was recommended to mandate business-level heat stress plans.
- Professor Andy Pitman (Net Zero Commissioner) stated extreme heat is Australiaâs most deadly yet preventable natural disaster and called for personal heat action plans like bushfire/flood plans.
- The Bureau of Meteorology warned of an upcoming El Niño system expected to bring prolonged dry conditions and heightened temperatures across Australia.
- Emma Bacon (Sweltering Cities) highlighted that disabled and elderly people are most vulnerable to heat stress, with many reporting isolation and lack of support during extreme heat.
- The NSW government has invested $45 million in greening projects to combat urban heating in Greater Sydney, Illawarra-Shoalhaven, Hunter, and Central Coast.
Points of Difference
Details reported by only one source:
- The NSW government completed 600 ceiling insulation installs in social housing in Western Sydney.
- Arlo Valmai, a Sydney renter, described living in a terrace where walls dripped condensation in summer and was cold enough to see breath in winter.
- Minister Penny Sharpe proposed changes to State Environmental Planning Policies to reduce heat impacts through planning.
- The Net Zero Commission was set up two years prior to the reportâs release (2024).
- The report noted that every 1°C temperature increase leads to a 20% rise in hospital emergency department visits for heat-related illness.
- 160,000 people are set to be removed from the National Disability Insurance Scheme (NDIS) amid concerns about support during extreme heat.
- Emma Bacon emphasized that disabled Australians fear losing NDIS support during an expected record-hot, dry period.
Contradictions
Conflicting information between sources:
- ABC states the NSW government has made progress on addressing heat stress in some ways mentioned by the review, while NEWSCOMAU frames the issue as a 'bombshell report' with no prior significant action.
