Premier Annastacia Palaszczuk has refused to rule out sending Queenslanders back to the polls if the November 25 vote delivers a hung parliament.

Ms Palaszczuk has insisted she would not enter into deals with crossbenchers to secure a return to the leadership, but on Tuesday would not say if voters would be forced to a second poll.

She touted her government’s success in working with crossbenchers to pass 138 of the 139 bills it introduced to Parliament since 2015, but when asked directly if she would take that approach again she said: “I need a majority.”

Her rival, LNP leader Tim Nicholls, has repeatedly ruled out forming a coalition with One Nation, but this week refused to answer questions about whether he would accept the minority party’s support, saying “regular Queenslanders” weren’t interested in “political games”.

It’s made him an easy target for Ms Palaszczuk, who has repeatedly warned voters of the “chaos” that would ensue if they supported either conservative party.

“The people of Queensland really have to stop and think, and think really long and hard about what sort of Queensland do you want,” she told reporters in Cairns.

“We don’t even know if those One Nation candidates are going to end up staying as One Nation members.

“Years ago when there was about 11 members elected to the Queensland parliament, they all just folded,” she said in reference to the 11 One Nation MPs who quit or deferred within months of being elected in 1998.

The party is polling strongly in some seats, and could hold the balance of power if those trends are realised next Saturday.

Ms Palaszczuk has made a string of commitments during her second tour of north electorates, announcing plans to establish an elite counter-terrorism unit and recruit 3700 teachers to cope with population growth across the state.

An emergency team and 85 new police officers will be based in the state’s north to respond rapidly to threats in regional areas, on the heels of an earlier commitment to build a $46.7 million counter-terrorism training centre in Brisbane.

The Premier has also pledged $1.73 million to fight carbon emissions from the Great Barrier Reef island resorts while continuing to back the $16.5 billion Adani coal mine project on the mainland.

The promise, made on the same day 15,000 scientists from around the world warned humanity is facing a climate change catastrophe, would encourage island resorts to make cases for solar, wind and gas generation.

The Premier said Labor was doing “everything we can to protect the reef”, but has refused to budge on her support for the controversial Adani project, despite the issue threatening to unseat deputy Jackie Trad in South Brisbane as voters begin to swing towards Greens candidate Amy MacMahon.
