A "vindictive" Palaszczuk Government is "cleaning the slate" of LNP laws without a mandate and against the desires of the Queensland people, Opposition Leader Lawrence Springborg said.

Ahead of the government's first estimates hearings, Mr Springborg said Labor was "aiming to expunge the past" and was wiping the LNP government's policies "from the face of the earth", governing as if the past three years before the last election didn't happen.

"We have a government here which has a scorched earth approach to what existed before the 31st of January this year, where it just wants to wipe it away from the face of the earth as if it didn't exist and has no plan with what to replace it with," Mr Springborg said.

"Now, I don't think Queenslanders voted for that and I don't think any reasonable Queenslander would believe that those things that existed before the 31st of January this year were so bad, that you basically just wipe the slate clean and start again.
