The newly re-elected premier pointedly failed to say whether Labor is considering payroll tax increases, after being challenged on the issue by the Liberal National Party.

Opposition Leader Deb Frecklington used her first questions of the new parliament on Thursday to quiz the premier over the four taxes announced during the election campaign, and whether the government is considering increases to other taxes.

Ms Palaszczuk only said her government will honour the commitments they took to the election.

"We took a set of commitments to the people of Queensland, we will honor that," she told parliament.

"We will remain tax competitive because that is where we see Queensland into the future."

Both the government and opposition were challenged during the election campaign to state how they will deal with the state's ballooning debt, forecast to hit $81 billion by 2020-21.

Traditionally, governments need to either cut services or raise taxes to deal with debt, however, both Labor and the LNP instead put forward debt action plans involving savings measures to halt debt increases.

Labor's proposed four new taxes are a 15 per cent wagering tax targeting agencies based outside the state, a luxury motor vehicle duty, a new land tax category for around 850 large property holdings and an increase on the surcharge applied to foreign purchasers of state land.
