Prime Minister Scott Morrison has promised a re-elected Coalition government will create 1.25 million jobs over the next five years.

Mr Morrison is in Brisbane to make the commitment, as the unofficial election campaign rolls on ahead of Parliament's return for 2019.

The pledge echoes one made by former prime minister Tony Abbott, who promised to create 1 million jobs in five years ahead of the 2013 election.

That goal was reached a few months ahead of deadline in 2017 by Mr Abbott's successor, Malcolm Turnbull, who heralded it as an indication of the Coalition's strength in managing the economy.

That was despite some analysts suggesting Australia's average jobs growth over the previous decade meant the nation was on track to meet that target anyway.

Mr Morrison is also expected to promise significant spending on "congestion-busting" infrastructure for south-east Queensland, which is home to a number of electorates the Coalition must cling on to if it is to have any hope of retaining government.

The speech will also be the platform for Mr Morrison to launch his pre-election manifesto, which he is dubbing a plan for a "strong economy and secure future".

Mr Morrison told AM the jobs would be full-time.

"That's been our record over the last five years, we promised one million jobs going into the 2013 election, Labor and others scoffed at that, said it couldn't be done — and we did it," he said.

He argued the economy would be weaker under a Labor government, but stopped short of declaring there would be a recession.

"You can't tax the economy to success," Mr Morrison said.

"I think I'm pretty blunt about it, the economy will be weaker under Bill Shorten and Labor."

The Prime Minister toured north Queensland last week, spruiking the Government's economic record and the alleged risks posed by Labor.

His counterpart Mr Shorten took his "Bill Bus" on a tour of regional centres including Gladstone, Rockhampton and Mackay, highlighting the stability in the Labor party when compared to the leadership turmoil that has wracked the Coalition over last two terms of Government.

"Scott Morrison is from another planet if he thinks that this economy is delivering for ordinary working people," shadow finance minister Jim Chalmers said.

"We've got falling confidence, stagnant wages, slowing growth, insecure work, high underemployment, high household debt, low savings at the household level.

"And we've got a Government too divided and too dysfunctional to focus on those important things."

Queensland is closely fought over at each and every federal election, and the Coalition holds 8 of 13 marginal seats in the key swing state.

Mr Morrison has repeatedly stated he will not call an election until after his Government delivers a budget on April 2.

The last opportunity for the Government to call a standard general election, or House and half-Senate election, is May 18.
