The Queensland government has refused to widen an inquiry into Star Entertainment to include other casino operators being investigated by regulators.

The Office of Liquor and Gaming Regulation has been probing allegations involving the Ville Casino in Townsville for six months, and The Reef Hotel Casino in Cairns for five months.

Those investigations were only revealed after a public inquiry into Star Entertainment’s suitability to hold a casino licence, led by retired justice Robert Gotterson, concluded on Monday.

Attorney-General Shannon Fentiman has refused to broaden the Star inquiry to include the two other casino operators, saying it’s already broader than the Bell inquiry, which probed Star in NSW.
