Voters expect the Turnbull government to win a very tight federal election, according to exit polls.
The Sky News exit poll on Saturday reveals 62 per cent of voters believe the coalition will win, including 39 per cent of Labor voters.
But a Galaxy Research exit poll of 25 marginal seats, conducted for the Nine Network, shows the election is too close to call.
It shows there's a swing to Labor of 3.4 per cent, which would give the opposition party 68 seats - short of the 76 needed to form a majority government.
Across the marginals, the coalition's primary vote is around 43 per cent, Labor 36 per cent, with the Greens on nine per cent. After preferences, its 50-50.
Senior Labor figure Anthony Albanese says it points to a good outcome for the opposition.
"We've been ahead in the polls for most of this term," he told the Nine Network.
"I'm hoping to get my incoming brief as a minister tomorrow."
According to the Sky poll, health and Medicare was the most important issue for 72 per cent of voters, followed by education with 63 per cent of voters - both key Labor policies.
The budget and economy came in third, followed by superannuation, negative gearing and building unions.
But company tax cuts - the government's key economic policy - came last, with just 29 per cent of coalition voters nominating it a very important issue.
Just 19 per cent of voters polled thought Labor would win.
