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.
