Polls have closed in Queensland, with most pundits expecting Annastacia Palaszczuk to lead her Labor government to lead to a second term with a small majority.
Polls have closed in Queensland with the Palaszczuk Labor government tipped to be returned to power in a very tight race, although the final results may not be known till preferences are sorted.
There will also be a lot of interest in the performance of Pauline Hanson's One Nation party, particularly in Canberra where the protest party has a lot of support in coalition-held federal seats.
Despite a 27-day campaign where both Premier Annastacia Palaszczuk and LNP leader Tim Nicholls blitzed electorates in both the regions and populous southeast of the state, opinion polls have barely moved.
The latest, the Newspoll in Saturday's The Weekend Australian, had Labor ahead of the Liberal National Party on two-party preferred basis of 52.5 per cent to 47.5 per cent. The most recent Galaxy, ReachTEL and Essential polls have shown similar results.
The Nine/Galaxy exit poll is predicting a Palaszczuk win, with the ALP to win up to 51 seats - four more than the 47 seats it needs to form a majority government. Again, the two-party results were 52 to 48.
Most pundits expect Labor to just squeak past the 76-seat mark needed to secure a majority government in the newly expanded 93-seat parliament, but not without losing seats in some key regional areas, including Townsville.
It's likely they'll pick up the seats they need to win from the LNP in Brisbane and possibly the Gold Coast.
The big issue for the LNP is the re-emergence of One Nation, which is sucking away its support from more conservative voters.
Despite a chaotic campaign by founder, Senator Pauline Hanson who is not standing in the state election, the protest right-wing party is polling up to 20 per cent in regional seats.
She's confident One Nation will get a groundswell of support, but won't nominate the number of seats they could pick up.
"We're going to win quite a few seats here in Queensland and I think that's going to carry across to the next federal election too," she told AAP.
She pointed to the 1998 Queensland election when One Nation won 22 per cent of the primary vote and 11 seats in parliament.
Ms Palaszczuk returned to her seat of Inala where her father Henry, mum Lorelle and sister Julia helped hand out how-to-vote cards.
She repeated her call for Queenslanders to choose Labor or risk the LNP going into partnership with One Nation.
"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.
Earlier in the day, Mr Nicholls was swamped by anti-Adani protesters as he arrived with his wife Mary to vote at a church in his inner-Brisbane seat of Clayfield.
"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.
Katter's Australian Party state leader Robbie Katter said he was excited about the impending result and hoped his rural conservative party could win up to five of the 10 seats it is running in.
The final outcome may come down to preferences. One Nation has put the Greens last on its how-to-vote cards, but put all sitting MPs second last which could make the distribution of preferences more complicated.
A further issue is the reintroduction of compulsory preferential voting for the first time in 20 years, instead of the previous vote one option.
About 717,000, or 23 per cent, of eligible voters across the state had already cast their ballot before polls opened at 8am on Saturday.
There were some issues at polling booths, candidates met with abuse, heckling and praise as they cast their ballot.
A One Nation volunteer was allegedly spat on and sworn at while handing out how-to-vote cards at a polling booth at Aspley.
