Labor's election win in Victoria is a mandate to scrap the controversial East West Link, Premier-elect Daniel Andrews says.

Mr Andrews sought advice from government bureaucrats about releasing the business case and all documents relating to the tunnel project.

Throughout the campaign, Mr Andrews has maintained the East West Link "isn't worth the paper it's written on" and has vowed to tear up the contracts, which were signed just before the Napthine government went into caretaker mode.

The Coalition took at least 37 seats and the Greens won their first ever seat in the lower house.

"This has been a rushed, botched and secretive project," Mr Andrews said of the East West Link project.

"I think Labor has a very clear mandate to release the business case and all documentation to do with this project, and then Victorians can see the true nature of this secretive tunnel.

"The road is not going to be built.

"I stand by each and every one of the election commitments we've made."

When asked why he did not mention the issue in his victory speech, Mr Andrews said he had "different priorities".

East West Link 'vital infrastructure': Prime Minister

In a statement, Mr Abbott congratulated Mr Andrews on the election victory and paid tribute to Denis Napthine, and his determination to push ahead with the road project.

"I share his commitment to the East West Link and I am determined to do what I can to ensure this vital national infrastructure project proceeds to completion," Mr Abbott said.

Earlier this week the Liberal government ministers claimed taxpayers would be hit with a $1.1billion compensation bill if the project was scrapped.

Newly elected Greens Lower House MP Ellen Sandell said she would use her position to hold Labor to their promise to tear up contracts for the project.

"Most people have been telling me they don't trust Labor, there are people in Labor who still want to build the toll road, so it's great that we've elected a Green who can hold them to account," Ms Sandell said.

"I'll be working there every single day to make sure that road's not built."

Mr Andrews said Parliament would be back to work before Christmas and the new ministry is expected to be sworn in mid-week.

"We're not going to be having any long summer breaks here. We're going to be right back to work," he said.

Mr Andrews said the first act to pass Parliament would be the Back to Work Act, to provide tax credits to businesses that hire young people and people who have been retrenched or unemployed for a long time.

"We won't waste a day getting on and getting Victoria back to work," he said.

He rejected the suggestion that Liberal Prime Minister Tony Abbott's performance had contributed to Labor's victory in the state poll.

"The Victorian people have voted for a positive and optimistic plan," he said.

"I am humbled by that. I'm honoured to be given this great responsibility.

"To be given the opportunity to govern is the greatest of gifts."

Liberals seeking new leader, deputy

It is understood the former planning minister, Matthew Guy, and the former treasurer, Michael O'Brien, were considered the front runners for the Liberal leadership after Dr Napthine announced plans to step down on Saturday night.

A ballot for the leadership is expected to be held on Tuesday or Wednesday.

Dr Napthine's deputy, Louise Asher, has also announced she will step down from her position, although she will stay on in Parliament.

Ms Asher said after 22 years in Parliament and 18 years as a frontbencher she felt it was "time for new blood" in the senior ranks of the Liberal Party.

"Given Saturday's result, it is now time for others to take on the responsibility of Liberal leadership," she said in a statement.

"Generational change at the top is needed and I wish to encourage a new person to take on the deputy's role."

Vote counting to resume on Monday

Sue Lang from the Victorian Electoral Commission said workers would be sorting through pre-poll, absent and provisional votes and sending them to the correct districts to be counted on Monday.

She said it was still too early to call some seats with close counts for the two-candidate preferred vote.

"There are still eight seats that have a very slim margin in the two candidate preferred area," she said.

"There's 49 to 50 per cent range, and those districts include Bentleigh, Frankston, Morwell, Shepparton, Richmond, Prahran, Ripon and possibly Melbourne."
