World welterweight champion Jeff Horn and Prime Minister Malcolm Turnbull were the opening acts for the respective Labor and LNP leaders' campaign launches.

Horn introduced Premier Annastacia Palaszczuk to Labor members at a low key event on the Gold Coast.

"There were lots of doubters last fight who didn't believe I couldn't beat Manny Pacquiao, the 11-time world champion in July," Horn said

"Annastacia Palaszczuk believed in me where many other people wouldn't.

"She backed my title defence and I back hers."

Ms Palaszczuk announced the $20,000 first home owners' grant will be extended for six months to June, incentives for businesses to employ out-of-work over 55s, and $107 million to attract and mentor new teachers.

"I will never promise something I can't deliver," she said.

In a jab to the LNP, Ms Palaszczuk gestured to a woman in the audience she said consoled nursing colleagues after they lost jobs under the Newman government.

She also reaffirmed her commitment to shun One Nation and capitalised on Opposition Leader Tim Nicholls' recent suggestions he will accept support from the party.

"Through his deal, Tim Nicholls is saying he prefers the values of One Nation; their values are his," she said.

"One Nation's candidates are his.

"Tim Nicholls is saying he prefers intolerance and exclusion."

Nicholls' pitch to the 'forgotten people'

Mr Nicholls made a pitch to potential One Nation voters the centrepiece of his campaign launch, pledging to help re-skill and re-train the middle-aged men and women "forgotten" by changes in the labour market.

The launch, held at a Brisbane rock venue this morning, was attended by Mr Turnbull and former premiers Campbell Newman, Rob Borbidge and Mike Ahern.

Mr Nicholls told the party faithful, technology and automation risk creating a "forgotten generation crisis" of "mature aged workers who have been sidelined by technology".

"I know that change is hard, especially when it's outside your control," Mr Nicholls said.

"I know that routine is easier than change. I know that change can be scary.

"An LNP government will provide greater support for mature-age workers who lose their job and need to retrain or reskill so they can continue working and contributing to their families and communities while maintaining their pride and their self-worth."

That would be done with a $20 million program to advise on training and offer "tech-savvy workshops".

Mr Nicholls again attempted to distance himself from the policies of the Newman government, promising a "new LNP government" would offer a positive change and not sell assets or force redundancies on public servants.

"I have said it, and I mean it, we made mistakes in the past that a future LNP government would never make again," Mr Nicholls said.

"We have heard you, we know you're frustrated — our policies are the answers to your frustration."

Mr Turnbull said his Government would be able to work with a Queensland LNP government to improve the economy.

"Only the LNP has the vision, and the plan, and the team, to get Queensland moving again," he said.
