The Australian Labor Party looks like it will win Government on Saturday as voting booths close in the east and an exit poll shows the Bill Shorten-led party popular with voters.
A Nine Network/Galaxy exit poll shows Labour ahead of the Coalition with 52 percent compared to 48 percent on a two-party preferred basis.
The poll reflects 3300 people in 33 electorates across six states, with every state showing a swing towards the ALP.
The swing ranges from 1.1 percent in Queensland, 2.5 percent in New South Wales and 3.2 percent in Victoria.
Labour frontbencher Chris Bowen told 7News that the early results looked promising, but he didn't want to call it.
"Polls haven't closed yet and I do think we're in for a long night, with pre-poll votes. And some sets aren't even counting pre-polls," he said.
Shorten voted on Saturday in Victoria, while current Prime Minister and Liberals leader Scott Morrison was in Tasmania in the morning before heading home to Sydney to vote.
One seat to watch will be Warringah, where former Prime Minister Tony Abbott may lose his seat - signally potential trouble for the Liberals.
If Shorten is to become Prime Minister, he would be the country's sixth in as many years.
