It turns out the state's budget took a strong hit from the former Queensland government's Strong Choices plan.

Treasurer Curtis Pitt said figures released to the current government showed more than $70 million had been spent on advertising, scoping studies and the like to prepare for the former government's asset privatisation plan.

Opposition Leader Lawrence Springborg said it was only right that the LNP prepared both Queenslanders and the assets for privatisation, but Mr Pitt, pre-empting what is going to be a fairly lacklustre budget, said it has left him with a hole.

The government will essentially have to repay the Queensland Treasury Corporation more than $40 million for work it undertook on behalf of the previous government for a capital works program based around Strong Choices.
