The 18-member ministry was announced today and will be sworn in on Tuesday, with the Government drip-feeding the announcements throughout Monday of its new-look ministry.

Ms Palaszczuk, who was the arts minister during the last term, will take the trade portfolio.

Yvette D'Ath will keep her role as Attorney-General, while Mark Bailey will step into the transport portfolio and retain the his job as main roads minister.

Stirling Hinchliffe has returned to the cabinet, while Di Farmer and Craig Crawford have been elevated to the front bench.

Earlier on Monday, Labor's caucus held its first post-election meeting in the Queensland Parliament.

Ms Palaszczuk was given a rousing welcome by her team, who she said had "a big job to do".

"We made a commitment to people that we would focus on jobs, health and education," she said.

"We made a commitment that we would work as hard as we possibly can to make sure people across our state can get access to employment.

"That is the number one most crucial issue that people raised with me throughout this campaign."

Ms Palaszczuk said in a statement this afternoon that her 18-member cabinet and five assistant ministers were the right mix of experience and regional representation to deliver greater economic prosperity and government services for all Queenslanders.

"Cabinet will have equal representation of men and women, and four of the five assistant ministers are women," she said.

"Our Government — of 25 men and 23 women — represents a state that will be soon be home to 5 million people spread across more than 1.7 million square kilometres.

"We will build on the success of our first term — working with business and industry to create more than 130,000 new jobs, restoring frontline services, investing record budgets in health and education, and strengthening our economy through investments in infrastructure and innovation."
