As New South Wales and Queensland residents grapple with dozens of frightening fires, Victorians have been told to expect their own "dangerous summer".
The state's environment department has predicted extreme heatwaves in the coming months.
Victorian Premier Daniel Andrews says that comes while there is plenty of material in the environment that could keep fires blazing if they spark.
"We know there's a lot of fuel load out there. We know we're going to have a long, hot, dry and dangerous summer," he told reporters in Melbourne on Tuesday.
"We're going to have a very challenging season."
Victoria has sent 500 of its own firefighters to NSW, where more than 50 fires are currently burning, 25 of which remain uncontained.
The state may send more support in the coming days, while ensuring it has enough emergency personnel to handle local incidents, Mr Andrews said.
He sent his best wishes to NSW Premer Gladys Berejiklian on Tuesday morning.
The Labor premier was unafraid to acknowledge the climate is changing, with fire seasons getting longer and blazes burning on both sides of the world at the same time in recent years.
That means Australia may no longer be able to reply on some aerial assets that have traditionally been shared between continents, while Victorians were being urged to plan their fire responses earlier.
But Mr Andrews has no plans to declare a climate emergency in Victoria.
"You can make a choice to sort of talk about these things, or you can act, and our view has always been to act," he said.
"There is no denying the science, there is no denying the very significant challenges we face."
