UPDATE, 9.10am:
SES south-west regional spokesman Brad Jew said the western end of the south-west region was now clear, while the storm was still moving through the Geelong end of the region.
He said there had been building damage and loose debris reported at both Port Campbell and Peterborough.
"Those jobs are just being completed now," he said.
"It was certainly a rough and windy night, but considering the amount of rain we received and the amount of wind, I'm a bit surprised there was not more damage," he said.
"The focus is now on the Geelong end of the region as the storms move through to the central part of the state," he said.
At 7.55am:
Warrnambool State Emergency Service volunteers had a busy morning with 15 call-out for trees down.
Warrnambool SES unit controller Stephen Bakker said there was a leaking roof earlier in the night but the tree calls were mostly received between 2.30am and 6.30am.
There were call-outs at Naringal, Childers Cove, Mailors Flat and Purnim while a tree caused issues after falling over power lines in Warrnambool's Laverock Road.
"There is a lot of water over roads and we would urge all motorists to drive to the conditions this morning and take extra care. We want everyone to be safe," he said.
"Warrnambool and district seems to have come out of it reasonably well considering the 100km/h winds.
"It certainly rattled the windows at my place, and I'm tipping most homes in Warrnambool," he said.
