Warrnambool SES unit controller Giorgio Palmeri and his team responded to a garage flooding around 7.15pm on Taits Road.
"We drained the water out of the garage using our pumps before we used sandbags around the area," he said.
South-west SES members warn drivers there are a number of trees down and to be vigilant on the roads.
