Show cause notices have been issued to the licensees of two Queensland casinos following a determination they are unsuitable to hold licences.

Attorney-General Shannon Fentiman says major failings at The Star Gold Coast and Treasury Brisbane were highlighted in a review conducted by former judge Robert Gotterson.

His inquiry was ordered after the NSW gaming regulator found Star Entertainment repeatedly breached the law, misled banks and allowed criminals to operate with impunity and gamble almost without restraint.

That probe also heard serious allegations about Star’s conduct in the northern state.

Ms Fentiman says the notices issued late on Thursday provided the two entities with the opportunity to show cause as to why disciplinary action should not be taken against them.

Their responses are due by November 25.

“While it is important that we do not pre-empt the outcomes of these show cause notices, new legislation ensures the government has a range of disciplinary options available following that process,” the attorney-general said.

These include increased fines of up to $100 million and the appointment of a special manager.
