Josh Frydenberg knows his seat of Kooyong is "tight" and isn't taking a win at today's federal election for granted.
Mr Frydenberg holds Kooyong on a nearly 13 per cent margin, but with high-profile human rights lawyer Julian Burnside and Liberal-turned-independent Oliver Yates also vying for the seat, he says he can't look into his "crystal ball" just yet.
The incumbent told reporters on Saturday, just after voting at North Balwyn Primary School, that he was confident a Morrison government would lead to a stronger future with the budget "back in the black" and criticised Bill Shorten's proposed tax increases.
Mr Frydenberg, who has held Kooyong since 2010, also hit out at dirty tactics during the election campaign, including having his door covered in swastikas.
"That level of antagonism, aggression and disregard for the horrors of history is unacceptable," he said.
Earlier on Saturday morning, Mr Burnside told reporters he isn't just "having a crack" at Kooyong - he is in it to win.
The first-time candidate was sure the climate change issue would get him over the line in the traditionally conservative Melbourne electorate.
"Climate change is overwhelming the main issue that people are worried about in this electorate and reality is that neither of the major parties has a serious plan to tackle climate change," Mr Burnside told AAP after voting in Hawthorn.
"They've both been supporting coal up north, and you can't tackle climate change unless you tackle coal.
"People in this electorate are concerned that their children and their children's children will have a world where they can survive."
He said it was time for change in the electorate.
"It's been held by conservatives since Federation and a lot of people have said... it's first time they felt that they've had a choice in the election."
