Qlders may never see asset sale studies

Queenslanders may never see scoping studies into the sale of public assets, the state treasurer says.

Tim Nicholls says the government has already received some of the studies, but warns they are very complex documents that contain a substantial amount of confidential information.

"We'll consider those scoping studies, they could have confidential information that would lead them to not being able to be released, particularly if the government tried to get the maximum value for things that it does own," he told reporters in Townsville.

The treasurer wouldn't commit to showing Queenslanders the documents.

"What we'll be bringing to Queenslanders is the information that is necessary in order to be able to make a decision around which way to go," Mr Nicholls said.

"I've never said those scoping studies will be released. I've always said we will conduct those scoping studies, they will be considered by government, they will contain confidential information."

The previous Labor government also refused to release scoping studies when it undertook unpopular asset sales in 2009-10.

Mr Nicholls says Queenslanders have three choices to increase revenue: increased taxes and charges, reduced services or the sale of assets.

The government has always said it won't proceed with any sales without an election mandate.
