Victorian upper house crossbench MP Fiona Patten wants a parliamentary inquiry into Crown Casino after allegations of money laundering and other dodgy dealings were revealed.

The Reason Party leader wants to suspend debate in the Victorian upper house to immediately address the allegations and the role of the Victorian Commission for Gambling and Liquor Regulation.

"The gaming commission is not doing it's job and the parliament needs to debate this," Ms Patten told reporters on Tuesday.

The serious allegations ranged from money laundering, drug dealing, organised crime and rigged machines, she said.

"This is the largest (single site) employer in Victoria, that has serious, very serious allegations against it. This is something the parliament should urgently deal with."

The cross-bench MP said she hoped to get support from the opposition and the government to deal with the issue in parliament.

But Liberal leader Michael O'Brien said the matter was being dealt with appropriately.

"We've said it's a job for the regulator, the regulator has very strong powers to get to the bottom of these matters," Mr O'Brien told reporters.

Earlier this month the state government ordered the regulator re-examine the allegations of money laundering raised by Nine media.

The casino is also subject to an Australian Criminal Intelligence Commission investigation and the federal government has referred the matter to the Australian Commission for Law Enforcement Integrity.

The NSW Independent Liquor and Gaming Authority will also investigate the sale of Crown Resorts shares to a Macau-based entertainment company.

Crown has denied the allegations, taking out full-page ads in Nine's newspaper rivals News Corp. Share this article
