Victoria Bushfires LIVE: Homes evacuated as fast moving grass fire threatens Little River

CFA Little River incident controller Geoff McGill said the fire is 60 hectares in size.

The CFA have 50 fire trucks at the scene, 220 firefighters and several large air tankers attempting to put out the blaze.

"The initial information we received is possibly there is three locations where the fire started and we are organising for investigators to go out and investigate formally," he said.

"The crews have done some good initial observations of those points of origin and kept them in a position to investigate them... we will be treating them as suspicious, yes."

Channel 7 has a great live feed showing aerial footage of the fire, including the blaze burning right up to the train line. 

There have been multiple cancellations, including the 1.30pm and 1.10pm Southern Cross to Geelong services and the 1.24pm South Geelong to Southern Cross.

Two extra strike teams have just been dispatched from Buninyong and Geelong.

They are meeting at Edgars and Narraburra roads in the Liver River area.

We hear a "significant" number of homes are at threat.

More than 110 firefighters are on scene, with CFA urgently requesting more.

Here's the flight pattern from one - it took off from Avalon at 12.31pm, which shows how quickly the CFA got on top of this fire.

Around 20 Little River residents have flocked to the centre of town, at the Little River General Store.

"They can’t get home because the roads have been blocked off," said Madde.

"There are a lot of parents going in to pick the kids up."

VicRoads are urging motorists not to travel on the Princes Freeway unless necessary.

"It's impacted by large plumes of smoke, again we ask people to delay non-essential travel, we have a VicRoads crew there waiting in case the freeway needs to be closed, ready to act if that needs to happen," a spokesman said.

A CFA spokesman told ABC Melbourne they were still assessing the damage but they believed some sheds had been affected.

"We have some vision of some sheds that are impacted, so not knowing exactly the extent, we have vision of sheds but no sign of any houses... some good work has been done to save some houses," he said.

Locals earlier told us two homes had been lost. It is unclear whether this information is correct.
