The Latest on Australia's general election (all times local):

6:20 p.m.

Votes are being counted after Saturday's Australian election, with senior opposition lawmakers gaining confidence they will form a center-left government with a focus on slashing greenhouse gas emissions.

A Galaxy exit poll found that the opposition Labor Party could win as many as 82 seats in the 151-seat House of Representatives, where parties need a majority to form government.

Polling booths in Australia's eastern states, where most of the 25 million population lives, closed at 6 p.m. Polls close on the west coast two hours later.

Opinion polls suggest the conservative Liberal Party-led coalition will lose its bid for a third three-year term and Scott Morrison will have had one of the shortest tenures as prime minister in the 118-year history of the Australian federation.

Opposition leader Bill Shorten had said Saturday morning he was confident Labor would win, but Morrison would not be drawn on a prediction.

Polling stations have opened in eastern Australia in elections that are likely to deliver the nation's sixth prime minister in as many years.

Opinion polls suggest the conservative Liberal Party-led coalition will lose its bid for a third three-year term at the election on Saturday and Scott Morrison will have had one of the shortest tenures as prime minister in the 118-year history of the Australian federation.

Morrison is the conservatives' third prime minister since they were first elected in 2013. He replaced Malcolm Turnbull in a leadership ballot of government colleagues in August.

The center-left Labor Party opposition under its leader Bill Shorten has been campaigning hard on more ambitious targets to reduce Australia's greenhouse gas emissions.
