Australia is facing the possibility of another hung parliament after voters swung away from the Coalition in a federal election which left Prime Minister Malcolm Turnbull potentially having to deal with independents and minor parties to stay in power.

Voters dumped more than 10 Coalition MPs with the Government suffering a 2.8 per cent swing against it.

With more than three-quarters of the vote counted, the Government was on track to claim 67 seats — down from 90.

Labor was also predicted to win 67 seats. Nearly a dozen were too close to call, and results may not be known until later in the week.
