The unseasonably warm weather affecting Australia for the last few weeks is set to come to a sudden end with a dramatic cold snap approaching.
The cool change will sweep across central and south-east Australia on Friday as the the mercury drops for millions.
Chilly temperatures are expected to hit much of Australias south, with Melbournes maximum on Saturday predicted to be six degrees below the September average.
By Sunday, the NSW south coast could be up to eight degrees lower than average.
A cold front travelling east towards Tasmania is expected to bring rain to the south, with the icy blast smashing south-east Australia expected to last into next week.
Its going to be almost winter-like this weekend for Tasmania and Victoria, Sky News meteorologist Rob Sharpe said.
That will then push up the NSW coastline through Saturday afternoon and evening.
But theres better news for northern Australia where it is expected to stay warm with Brisbane getting hotter over the weekend.
A cold snap will hit Australia in the coming days with the south-east (circled) the worst affected
