Floods and Heatwaves Threaten Millions in Australia

A new national climate risk report warns that rising seas, extreme heat, and other climate impacts could put millions of Australians at risk in the coming decades.

By 2050, approximately 1.5 million homes along the coast could face flooding, and that number may double by 2090.

The Torres Strait Islands are especially vulnerable, threatening Indigenous communities’ homes, traditions, and cultural heritage.

Heatwaves are projected to become deadly, with deaths in Sydney potentially rising by 400 percent.

Property losses may exceed $400 billion by mid-century, increasing even further by 2090.

Experts and environmental groups warn that ongoing fossil fuel projects and gas developments could undermine Australia’s green transition, putting the country at a critical crossroads for climate policy and urgent action.
