Elton John has been escorted offstage after torrential rain interrupted his outdoor show in Victoria's Yarra Valley.
The wild weather struck about an hour and a half into the performer's Friday night set, A Day on the Green festival organisers said.
"Unfortunately due to tonight's short but heavy downpour that occurred 95 minutes into Elton John's set resulting in damage to musical instruments and monitors on stage, the show could not continue," a post on the event's Facebook page said.
"We too are upset about the impact of the weather on tonight's show. Please hang on to your tickets to await further information."
Video posted online appeared to show rain and wind lashing Elton John and his piano as he performed Funeral For A Friend at the front of the stage.
Crew could be seen escorting the star away and rushing to cover music equipment.
Earlier on Friday the state's emergency services minister had warned of flash flooding and rain after a day of intense heat and humidity that caused power outages and prompted calls to reduce electricity usage.
