A GRASSFIRE is burning out of control near Little River, 30km northeast of Geelong.

The blaze broke out just before 5pm on Little River-Ripley Rd.

The CFA said 13 vehicles were trying to bring the blaze under control, with more than 10 additional crews currently travelling to the fire.

The fire jumped to the Balliang side of Little River just after 5pm.

Water-bombing aircraft may be called to assist firefighters.

It is not known how many hectares have been destroyed.

CFA State Control Centre spokeswoman Sonia Maclean said another fire north of the East Gippsland town of Ensay, which covered 240ha, was brought under control yesterday.

Residents of Ensay had earlier been told to remain vigilant as the blaze burned out of control around 7km north of the town.

Meanwhile, firefighters are hoping to bring a blaze in Victoria's southwest under control today, with more than 2700ha already destroyed.

The CFA has worked overnight to fight the fire, which has ripped through grassland and national forest between Port Fairy and Nelson, next to the South Australian border.

CFA State Control Centre spokesman Jason Leigh said the Kentbrook fire, near Mt Richmond, had burnt more than 2700ha.

He said the fire was in low-lying swampy terrain, which made ground access difficult.

Crews hoped to burn to control lines today with the help of seven fixed-wing planes, seven helicopters, 35 ground vehicles and a couple of bulldozers.

Mr Leigh said a thick smoke haze from the fire could be seen as far away as Horsham and the Mallee.

The blaze ignited about 18km southeast of the Mt Richmond National Park along the Princes Hwy on Friday afternoon.

No homes or property were threatened by the fire.

Mr Leigh said a Victorian strike team had also been sent to help NSW crews fight a fire in Ournie, on the border with Victoria.

He said it was feared a wind change could push the fire into Victoria later today. The 300ha fire is about two hours from Tallangatta, in Victoria’s north.
