James Packer is expected to oppose the Federal Government's pokie machine reforms, at Crown's general meeting in Melbourne.
Mr Packer's Crown Ltd owns The Crown casino complex in Melbourne and the Burswood casino in Perth, two of Australia's biggest gaming venues.
In his first entry into the debate surrounding the government's proposed pokie machine reforms which aim to stem problem gambling, The Australian reported he would tell Crown's annual general meeting on Thursday that he did not support it.
"There is no evidence that mandatory pre-commitment will be effective in tackling problem gambling but it will hurt recreational players and that will cost jobs (and) investment and cost the state government tax revenue," Mr Packer is expected to say.
The comments come after Opposition Leader Tony Abbott told a 1000 people at a Clubs NSW rally that he predicted his party would not support the legislation in parliament.

But independent MP Andrew Wilkie said he is confident the reforms will become a reality.
Under the government's plan, players would have to set limits on their losses before they started gambling on high-intensity machines that take large bets.
Low-intensity machines would be reprogrammed to cap losses at $120 an hour rather than $1200.
"When these reforms are realised, he'll (Mr Abbott) find it very, very difficult to overturn," Mr Wilkie told ABC Television on Wednesday night.
