NSW casinos could cop $100 million fines with board members and executives held liable if operators are found to have committed "serious wrongdoing".

The NSW government will hand the powers to the state's newly minted casino watchdog if new legislation passes state parliament after it's introduced next week.

It follows separate inquiries revealing damning evidence of the facilitation of money laundering at Sydney's two casinos, Crown and the Star, by gambling junkets linked to overseas criminal gangs.

The establishment of the NSW Independent Online Casino Commission was part of the state government's response to the inquiry into Crown, headed by former Supreme Court judge Patricia Bergin.

Tough new conditions were placed on Crown so it could keep its doors open in Sydney after the Bergin inquiry found it was unfit to hold an operating license.

Hospitality Minister Kevin Anderson said the commission would also have powers to investigate and Online Casino enforce compliance with regulations.
