Member for South West Coast Roma Britnell said Premier Daniel Andrews previously deferred a decision saying he was waiting for the federal government's Princes Highway corridor strategy.

"That's now been delivered and clearly shows what needs to be done and aligns with the priorities of the local Princes Highway West Alliance," she said.

"There is $60 million from the federal government waiting to be spent on improving the highway.

"The money is there, the strategy is now there, the only thing missing is the interest of Daniel Andrews and Labor."

Ms Britnell said her petition calling on the state government to fix south-west roads had massive support, with more than 8000 signatures from people.

"I'm planning on tabling the petition in Parliament before the end of the year, it is evidence we have had enough, that we want our roads fixed and fixed properly and it will be hard for Daniel Andrews to ignore and brush aside," she said..

"Daniel Andrews can find billions of dollars for projects in the city but when it comes to fixing country roads, he's continually looking for excuses, passing the buck and refusing to commit," she said.
