Clunes Caravan Park manager Les Eastcott said intruders ransacked a van on Saturday night, allegedly making off with a PlayStation.

He said would-be thieves were also disturbed trying to steal gas bottles.

"It's pretty lousy when people try to take benefit of some other person's misfortune," Mr Eastcott said.

The town was hit by flash flooding on Saturday morning, when, in a couple of hours, the normally docile Tullaroop Creek turned into a torrent.

Several long-time residents said they had seen nothing like it.

Mr Eastcott said about five units at the park, which is next to the creek, had been affected by flooding.

Two vans had been occupied by permanent residents.

He praised locals who had volunteered their time to help with the clean-up.

"We've had people turn up at the door and say `what can I do?' "

Across the other side of the creek, Clunes Football Club president Doug Garth had begun cleaning up at the ground yesterday morning.

On Saturday fast-rising water covered the oval and was high enough for someone to ride a jetski on it.

But the flood also made its way into the clubrooms, damaging fridges and leaving thick ooze on the carpets.

The netball court, paid for by the club without government help and used for the first time in April, would need extensive repairs.

Mr Garth said the damage bill would be "in the thousands".

Karen Byrnes' front room was inundated, as was the shed where her husband Mark had been restoring Harley-Davidson motorcycles.

She said the water began rising rapidly between 10am and 11am.

"Within 10 minutes it had risen eight inches (203 mm)," Ms Byrnes said.

Opposition leader Ted Baillieu and deputy leader Peter Ryan toured the town yesterday morning.
