Treasurer Tim Nicholls said more than 16,000 people had “had their say on how to lower Queensland's debt to a sustainable level” through the website in its first week of operation, with more than 76,000 unique visits and about 337,000 page views.

“This clearly indicates that despite the unions' scaremongering and tricky tactics, Queenslanders know we have a real challenge to tackle that requires strong choices to be made,” Mr Nicholls said in a statement.

But opposition treasury spokesman Curtis Pitt accused the government of playing its own tricky tactics by including private investment into the electricity grid as a solution to lowering the debt.

Mr Pitt said an option on the website reduced the gross debt level from $80 billion to $51.6 billion when users selected private sector investment, which he said was a “fundamental flaw”.

“That $28 billion in reality refers to future investment in that network, it is nothing to do with the current level of debt in Queensland,” he said.

“Tim Nicholls has been going around Queensland talking to people about this Strong Choices website saying this is a chance for them to play a part in doing what really should be his job.

“Ultimately what it does is point people to a flawed website that is blatantly misleading Queenslanders.”

Mr Pitt said the website was “fatally flawed, misleading and must be removed immediately”.

Meanwhile, the Electrical Trades Union has called for a debate between economist John Quiggin and the Treasurer on privatisation.

In a report commissioned by the Victorian branch of the ETU and released in February, Professor Quiggin concluded privatisation of the energy sector had been a “failure”, with the long term benefits of states retaining power assets outweighing the short term financial gain of selling.

Mr Nicholls has not yet responded to the invitation.

The government has budgeted $6 million for the "Strong Choices" campaign.
