New modelling reveals tens of thousands of residents in Bullwinkel face heightened risk from climate-driven disasters, throwing a volatile factor into an already high-stakes campaign.

This month, the Climate Council ranked Bullwinkel eighth on its list of the top 10 federal electorates with the most at-risk homes with threats from climate-driven extremes like floods, bushfires, cyclonic winds, and coastal inundation.

The analysis found 41 per cent of homes in the electorate were at risk, with nearly 13,000 residents at “high risk” of disaster. That would more than double to 30,000 by the end of the century if no action was taken to address climate change.
