Queensland budget estimates will kick off with the state's premier and treasurer set to be grilled by both the Liberal National Party opposition and potentially one of their own Labor colleagues.
Bundamba MP and former police minister Jo-Ann Miller was a vocal interrogator during last year's estimates hearings after she resigned as a cabinet minister following a series of public gaffes.
In particular, she took her own government to task over the issue of black lung in coal miners, which eventually saw her head the inquiry into the re-emergence of the disease.
Ms Miller did not give an indication of what issues she would be bringing to the table this year, but encouraged all MPs to ask questions of the government.
"I will be attending every estimates committee again this year. I broke the mould last year in relation to attending," Ms Miller told AAP.
"I think all members of the Queensland Parliament should consider attending estimates committees. It's the time when every MP can ask questions directly of the ministers, which is very difficult to do in the ordinary sittings of parliament."
Premier Annastacia Palaszczuk will likely face questions about issues including the royalties deal for Indian mining giant Adani and turmoil in her office involving her chief-of-staff.
Treasurer Curtis Pitt is expected to be asked to explain several budget measures, with the opposition accusing the state government of allowing debt to creep without the means to pay it down.
