Minor parties are once again set to be in a powerful position if, as polls suggest, Labor and the LNP fail to win a majority in the Queensland election.

It is possible Katter's Australian Party, a resurgent One Nation and perhaps the Greens will decide who governs in another hung parliament.

Both major party leaders have strenuously denied suggestions of deals or partnerships; but in the cold light of day after the election would they refuse the support of One Nation or other cross benchers on the floor of Parliament to form a minority government?

So what do the minor players stand for and who would they support?

Pauline Hanson's One Nation

One Nation's growing popularity has pollsters suggesting they could collect a number of regional seats.

While it is unlikely they will reach the heights of the 1998 state election with a haul of 11 seats, Labor and the LNP are nervous about One Nation's growing regional support base.

Candidates to watch include Jim Savage in Lockyer, Scott Bannan in Logan and Mr Dickson in Buderim.

Former senator Malcolm Roberts will contest the seat of Ipswich.

As to who the party would back in a hung parliament scenario, Mr Dickson said the party is ready to negotiate.

"We'd love to win government but I'm always a realist," he said.

"If we end up with a balance of power in Queensland, that means Queensland wins, because we're putting people before politics, very simple equation.

"We're willing to do a deal with whoever wants to do a deal with us. And that means we have a line in the sand. Everything that we've committed to, all the policies that we've put in place, that's our baseline."

Queensland Greens

The Greens are looking to secure their first ever seat in Queensland Parliament and rate their best chance with first-time candidate Amy MacMahon.

The electorate has undergone a significant boundary redistribution and now closely resembles the local government seat won by Greens councillor Jonathan Sri in 2016.

The party has predicted Ms MacMahon is less than 500 votes away from claiming victory.

"We won't support an LNP Government, we'd be more likely seeking a deal with Labor," she said.

If they do secure a seat on the crossbench, Ms MacMahon said she would find it difficult to work with One Nation.

"I'd also say we wouldn't be doing a deal with One Nation but I would say that we're a grassroots party and any of these decisions are made with our members," she said.

Katter's Australian Party

Independent speaker Peter Wellington helped Labor form minority Government in 2015, but the Katter MPs — Robbie Katter and Shane Knuth — have supported Annastacia Palaszczuk on many occasions in the past term.

But the party wouldn't guarantee support in any direction this election.

"(We'd support) whoever shows serious commitment to regional Queensland," Mr Katter said.

"KAP has a specific agenda to reconstruct our state and we are particularly focused on regional Queensland, we're the only party exclusively running in this area."

"Whichparty best answers those problems for Queenslanders deserves our support."

The redistribution of electoral boundaries may impact the re-election chances of Mr Knuth, whose former regional western seat now takes in a significant portion of the Far North.

But there is one advantage for the outback MPS — One Nation has ruled out running candidates against them.
