It seems like an age ago now, but pre-COVID, Australia was battling another crisis with its 'Black Summer' bushfires – the worst in living memory. In this episode of the Australian Aviation Podcast, former NSW fire commissioner Greg Mullins explains why climate change means bigger fires will soon be a regular reality. He also talks to host Adam Thorn about the state of play with our aerial firefighting fleet and why the federal government must do more to prevent another disaster. Finally, Mullins speaks about the reality of fighting fires on the front line, and why it runs in his blood.
