Three million Queenslanders are heading to the polls to decide who will lead the next state government.
After 28 days on the hustings, Premier Annastacia Palaszczuk and Liberal National Party leader Tim Nicholls joined the battlers, city slickers and undecided in the fight for their political lives.
But it could be days before a final result is delivered, with counting of booths and pre-polls to get underway on Saturday while the hundreds of thousands of postal and absentee vote calculations begin on Sunday.
It took more than a week before Labor could claim power in 2015, after the LNP was resoundingly dumped after a single term.
This time, the resurgence of One Nation and return of compulsory preferential voting will further complicate Labor and the LNP's chances of winning a majority government.
Ms Palaszczuk and Mr Nicholls are both in for a tough fight, with Labor claiming a narrow lead over the LNP in the latest polling.
The premier started the day on the Gold Coast before returning to her southwest Brisbane electorate to cast her vote at Inala State School.
Mr Nicholls helped his 78-year-old father, Peter, at a polling booth in his blue-ribbon Clayfield seat.

Mr Nicholls and wife Mary were heckled by chanting 'Stop Adani' protesters as they stopped outside the St John's Anglican Church in Hendra, where the Liberal National Party leader took a final dig at Premier Palaszczuk.
"I'm feeling really positive, we've got a great message, we're talking about cheaper power, we're talking about jobs, and jobs for regional Queensland that Annastacia Palaszczuk doesn't want to deliver," he told reporters.
Mr Nicholls, who enjoyed a smooth four-week campaign, ended it on a sour note with an embarrassing gaffe on breakfast television.

"If you want a stable majority government, then the best thing to do is to support your LNP, One N... uh ... LNP candidate at the election," he said before blaming the mistake on a tiring campaign.
Mr Nicholls had done his best to distance the LNP from One Nation but had not ruled out accepting their support to form a minority government, and the stumble won't help traditional LNP voters worried about an alliance with Pauline Hanson's party.

Premier favoured to retain power
Ms Palaszczuk continues to play the underdog card but the premier is favoured to retain power.
Ms Palaszczuk has returned home after an election campaign spent crisscrossing the state, casting her ballot at Inala State School.
The premier repeated her mantra that voters have a "clear choice" box between her government or the Liberal Nation Party with One Nation support.
"That (choice) is whether they want to continue with a stable, hardworking, decent government, or do they want to put that at risk with Tim Nicholls as Premier with Pauline Hanson," the premier told reporters.
The Inala MP also urged LNP voters uncomfortable with One Nation to vote for her just one time, to avoid "cuts and chaos".
The Inala ballot box was nearly deserted at 11 o'clock on Saturday morning, an indication that large numbers of people have already cast their ballots in pre-polls.

The Electoral Commission Queensland estimates 23 per cent of Queenslanders have already voted, with 240,000 casting their ballots on Thursday and Friday alone.
Ms Palaszczuk didn't want for support, despite the lack of voters at Inala State School. Her father Henry, mother Lorelle and youngest sister Julia all handed out how to vote cards.
The premier said it was good to be back in Inala at the end of a long month of campaigning.
"It's always lovely to be here," Ms Palaszczuk said.
"The people of Inala in this electorate here drive me every single day, as do the people of the state, so I just want the best for families."
Polling puts Labor marginally ahead of the Liberal National Party 52 per cent to 48 in a two-party-preferred basis but the reintroduction of compulsory preferential voting has clouded the results.
The rise of One Nation, major boundary redistributions and numerous three-cornered contests has the major parties on tenterhooks as they expect the race to go down to the wire.
A victory will write her name in the history books, making the Inala MP the first Australian woman to win two elections at either state or federal level.
