Star Entertainment has been called to give evidence at an inquiry into proposed gambling and money laundering laws in Queensland.
A parliamentary committee is probing the legislation introduced after probes into Crown and Star in multiple states.
The changes would allow more cashless gambling, and impose penalties of up $50 million for legal breaches.
Legal Affairs and Safety Committee chair Peter Russo says Star and Townsville operator Reef have been asked to give evidence at the inquiry starting on July 11.
He says the bill is intended to stamp out money laundering and other "unsavoury" practices at casinos.
"That's the crux of what the legislation would hope to achieve," Mr Russo told AAP on Tuesday.
Lawyers for a NSW gaming regulator inquiry into Star submitted the operator was "not fit" to hold a Sydney casino license on Tuesday.
Mr Russo said the proposed Queensland laws won't stop laundering when operators themselves were involved.
"I don't know that (the bill) would eliminate it," he said.
"Because what they (Star) were basically doing is they were encouraging high rollers to participate."
Attorney-General Shannon Fentiman has resisted ordering an inquiry into the suitability of Star Entertainment to hold a casino licence, but the proposed laws would allow her to do so.
Star is the proponent behind the $3.6 billion Queens Wharf development, an integrated casino and resort in the Brisbane CBD.
Mr Fentiman said further legal changes in Queensland could be considered at the conclusion the NSW probe into Star.
The proposed casino bill would also force operators, licensees and lessees to self-report legal breaches and expand the Queensland's government's power gather information about their operations.
Mr Russo said other gambling entities, game manufacturers, clubs and pubs, and charity groups have been asked to give evidence at the inquiry.
Queensland's Crime and Corruption Commission, the NSW Independent Liquor & Gaming Authority and the Victorian Commission for Gambling and Liquor Regulation are invited as well.
