Mr Andrews said on Sunday that Victoria’s firefighters were equipped with their largest air fleet ever as emergency services flagged the Gippsland region and north-west of Victoria as at greatest risk this fire season.

"[Emergency services] will be called upon this year. We will experience fire. The key point is, our CFA, our firefighters, our emergency services, they're playing their part. It's up to the rest of us as Victorians to do our bit," he said.

Mr Andrews said the government and emergency services had developed a "confronting and challenging" advertising campaign this year to address complacency they detected among Victorians last fire season, when more than 4500 fires hit the state.
