Revellers at the annual Falls Festival on Victoria's Great Ocean Road are leaving after organisers cancelled the rest of the four-day event due to extreme weather.
About 9000 festivalgoers are making tracks from the 27th annual music and arts festival in Lorne, ahead of gates closing at 9am on Monday.
The four-day festival opened on Saturday and was due to have revellers partying into 2020.
But the predicted extreme weather conditions in the Otways and the surrounding region poses too great a risk to health and patron safety, organisers say.
"We are gutted to make this call but the safety of our patrons, artists and staff is our main priority," Secret Sounds Co chief executive Jessica Ducrou said.
"Please take care getting home safely."
The decision has been made with emergency stakeholders and fire authorities, she said.
"It is clear that we have no other option," a statement from the festival reads.
Headliner Halsey announced on social media to fans that she'll play a "good old fashioned dirty show in Melbourne" at The Forum on Sunday from 10pm instead.
"Lorne falls ticket holders get priority access to the box office tonight, but anyone can come. All profits are going to fire relief. Drive on up and let's do this," she tweeted.
A total fire ban is in place across the state tomorrow.
Extreme heat, wind, possible storms and fire risk are on the cards for Monday in the area, Bureau of Meteorology senior forecaster Dean Stewart told AAP.
"It is going to be hot, it is going to be windy there is some potential for storms coming across," Mr Stewart said.
"The heat and the wind will push the fire danger up to severe to extreme around parts of the state. If you have all those people in a bush environment ... it is not a good recipe."
Food, medical stations and toilets will remain open on Sunday but there won't be any music playing or bars open.
Partygoers are urged not to go back to Lorne or other coastal towns as the same extreme weather conditions are in place, while the Otways faces an extreme fire risk.
An information centre will be set up in Geelong.
Full ticket refunds - including booking and payment processing fees - will be processed from Monday back to the original purchaser's credit card.
Falls Festivals events in Byron, Marion Bay and Fremantle remain unaffected.
