Crossbench MPs have lashed out at the government and opposition for rejecting a parliamentary probe into explosive allegations against Melbourne's Crown Casino, accusing Australia's major parties of being unduly influenced by the powerful gambling and poker machine industry.

Independent MP Andrew Wilkie and crossbench senator Nick Xenophon called for a federal inquiry after releasing the accusations that Crown illegally tampered with poker machines, undermined federal government efforts to track money laundering, and ignored domestic violence.

The move was backed by the Greens and fellow crossbencher Jacqui Lambie but the Coalition and Labor quickly joined forces to oppose it, arguing that state authorities were responsible for gambling and casino oversight.

In the 30-minute video interview presented to Parliament on Wednesday, three unidentified whistleblowers – said to be former Crown employees – also accused the Victorian Commission for Gambling and Liquor Regulation of being "complicit" in covering up alleged misconduct, a claim the regulator promised to investigate.
