As temperatures begin to soar, Port Fairy CFA captain Garth Palmer said long grass along the state and council-managed roads in Moyne Shire was drying and posed a fire risk.

"It's very long this year, it's a bigger problem than most years," Mr Palmer said.

"You get a car pulling out on the side of the road, with long grass it could start a fire. Restrictions come in on Sunday. The grass is still green but it's going to dry off."

Kirkstall resident Helen, who did not want her surname published, said she was concerned about long grass on council-managed roadsides in the Koroit district.

"Nothing seems to have been done this year," she said. "It rained late, but they should be about doing something now."

Regional Roads Victoria south-west director Emma Miller-Olsen said authorities last cut grass in Moyne Shire in late October and early November.

"Our crews are back out undertaking further slashing across the region over the coming weeks - which will include the Princes Highway," she said.

Moyne Shire chief Bill Millard said the region had experienced a "late start to summer" and "considerable vegetation growth".

He said the council had identified priority roads for burnoffs or slashing based on a risk-assessment to create fire breaks for communities.

The council refused to release that list of roads, stating it was under review, but said it included about 625 kilometres of roadsides to be sprayed, 658 kilometres to be burnt and 375 kilometres to be slashed.

"Burning is the preferred method of management as it promotes the growth of native grasses," Mr Millard said.

"As burnoffs cannot commence while the grass is still green, the CFA plan to commence burnoffs in February. Council has begun preparing fire breaks along identified priority roads by spraying and grading roadside edges."

Moyne mayor Daniel Meade said the council was also advocating to the state and federal government to have legislation changed to help farmers drove on roadsides.

"It would help us keep roadsides under control," Cr Meade said.

Councillor Jim Doukas said the council could consider extra contractors in coming months if it didn't have the capacity to reduce roadside vegetation.

Moyne's municipal fire prevention officers have also inspected all townships in the shire, and have issued 285 fire prevention notices to property owners.
