Queensland’s opposition leader is standing by allegations she made about government corruption today despite having no evidence to take to the Crime and Corruption Commission.

Splashed in black and white in today’s Courier-Mail, LNP leader Deb Frecklington wrote in a column that “corruption and criminality is tolerated at the highest levels of government”.

She said the “lawless” union, the CFMEU, enjoyed "unfettered access" to the Palaszczuk government in return for political donations and other forms of support.

But when she was pressed for evidence by civil libertarians there was none that could be taken to the watchdog.

“How much more evidence do you need? We have seen the unions dragged before the courts 10 times in the last 18 months. They've been fined $2.4 million,” she said.

“Nobody is saying that Labor has done anything illegal,” she added.

"What we are saying is that Annastacia Palaszczuk is turning a blind eye to corruption and criminal behaviour by continuing to accept money and continuing to open her arms wide for the CFMEU in Queensland to have that sort of influence over government."

The Queensland Council for Civil Liberties vice president Terry O’Gorman said Ms Frecklington needed to “put forward the facts” or acknowledge her allegations were a “gross exaggeration”.

Acting Premier Jackie Trad, filling in while Ms Palaszczuk is on a 10-day trade mission, dismissed the column as a stunt.

“This is more about a desperate leader who is under pressure in her own party that is seeking to raise her profile,” she said.
