Victorian independent MP Cathy McGowan has refused to say who she would support in the event of a hung parliament.

Ms McGowan retained the seat of Indi in north-east Victoria with a swing of 4.5 per cent, seeing off a challenge from former Liberal frontbencher Sophie Mirabella.

With the possibility of a hung parliament looking increasingly likely, support from crossbench MPs will be crucial to whoever wins government.

Speaking in Wangaratta, Ms McGowan did not say who she would support.

"This morning I did have a phone call from the Prime Minister [Malcolm Turnbull], who did congratulate me on the win, which was lovely to receive. I also congratulated him on winning his seat," she said.

"He's very confident he can form a majority government, and we've agreed to stay in contact for the next couple of days as the national situation settles down.

"It's clearly very fluid at the moment."

When asked about her position if there was no clear majority in the Lower House, she said: "We'll cross that bridge when we get there."

Ms McGowan said she had a "good working relationship" with Mr Turnbull, but her success was proof people were tired of the way campaigns and governments were run by the major parties.

"I think the Prime Minister's very confident that he can get the numbers and I wish him luck as he goes around doing that," she said.

"Clearly I've got a lot to contribute to working with the government. There's a huge message out of north-east Victoria about how people want to do politics."

She also moved quickly to dismiss rumours she could become Speaker, saying she had no interest in the role.

"I'm very happy being the Member for Indi, that's 100 per cent of my focus and I'll really look forward to taking our agenda on those national issues that we need, but also local issued around renewable energy, jobs, arts and public transport," she said.
