A push for changes to gambling laws will come to a head on Tuesday as negotiations between Labor and the coalition are put to respective party rooms to be approved.
Under the proposed changes, Australians would have access to a one-stop shop allowing them to opt out of online betting ads, put limits on commissions for betting agents, and restrict incentives for punters.
Treasurer Jim Chalmers said the changes were substantial.
"They will make it much easier for people to opt out of this advertising, at the same time as we make it easier for the regulator to enforce the rules around inducements," he told ABC TV on Tuesday.
"These are important additional steps, and we will be seeking their passage through parliament in coming days."
The treasurer said the gambling industry, not taxpayers, would not be paying for the additional measures.
Under the reforms to be brought in by the federal government, betting ads would be halted on television between 6am and 8.30pm, and be banned from stadiums, jerseys and during live sport.
However, the government had come under fire for not going as far as a 2023 report by late Labor MP Peta Murphy, who called for a total phase out of gambling ads.
Feedback in a Senate report released on Monday on the gambling changes noted many of its recommendations had not been included in the reforms.
Support was needed by either the coalition or the Greens to get the bill over the line.
Opposition health spokeswoman Anne Ruston said she was confident the coalition would back the deal, before it is expected to be voted on in the lower house later on Tuesday.
"(It) will see vulnerable Australians who have gambling problems and particularly children protected from the predatory behaviour of gambling companies, but I'm not going to get ahead of the party room," she told ABC Radio.,
"There are a lot of Australians who don't mind going to the horses and having a bit of a flutter. We don't want to stop them from doing that, but we do definitely need to stop this predatory behaviour."
Most minor parties are unlikely to back the reforms.
Greens Senator Sarah Hanson-Young has demanded a complete ban on all online gambling advertising and called for the establishment of a national regulator.
An opt-out measure did not go far enough, she said.
"I've got no idea how the government thinks this is going to operate, and the idea that you can opt out of all corners of the internet," she told ABC's 7.30 on Monday.
"It just beggars belief that any serious policy brain has put this forward."
The report also included damning claims from independent Senator David Pocock, who said the government had failed to extricate sport from its relationship with gambling, and in doing so, failed to protect Australian children.
Independent MP Sophie Scamps savaged the agreement between Labor and the coalition.
"Weak. Piecemeal. Pathetic. That's how I'd describe the deal the major parties have struck on gambling reform," she said.
"Australians are the biggest losers to gambling in the world and over 400 die by suicide each year linked to gambling addiction."
