Suncorp CEO Steve Johnston has demanded that “science and reality” guide post-bushfire reform, rather than ideology or "partisanship".

In an at times cutting piece published on LinkedIn, Mr Johnston warns against inquiries following the devastating fires becoming “talkfests”.

And he says that investment in disaster mitigation is required now, as climate change alters Australia’s relationship with extreme weather events.

“We do not need talkfests designed to reassure an exhausted and sceptical constituency that something is finally being done,” he says.

“Australia needs a comprehensive strategy and plan for action to far better mitigate against such events and to make us more resilient when they do occur.”

Mr Johnston warns that a lack of action could lead to increasing numbers struggling to access insurance.
