Punters will still be able to use credit cards to buy lottery tickets despite the strong objections of gambling reform organisations.
Credit is set to be banned for online wagers such as sports betting, but a parliamentary report has recommended carving out an exemption for lottery games citing their "relatively lower harm".
A Senate committee was exploring if "other harmful interactive wagering services" should be included in the ban, and decided to keep reviewing it during the next year.
It's unlikely to sit well with reform organisations that told the inquiry people should not be able to bet with money they don't have.
The Alliance for Gambling Reform argued the harms caused by online lottery and Keno products were being understated, noting the products were also exempt from the new self-exclusion register.
"This means people that have signed up to the register can still gamble online on these products ... on the Lott app you can easily spend $10,000 on tickets immediately, and Keno is a maximum of $1000 every three minutes," it said in a submission to the inquiry.
"The Alliance is becoming increasingly concerned about lottery and Keno products as they move online."
Financial Counselling Australia agreed and said exempting lottery games would have unintended consequences.
"Carve-outs are a mistake and lead to market distortions … put simply, money flows to whatever segment gets a carve-out," it said in its inquiry submission.
The committee, chaired by Labor senator Karen Grogan, said lottery harms were "considered sufficiently low to justify their exemption".
It pointed out that charities and community groups often raised funds through lotteries, primarily via credit cards.
"The committee appreciates the role lotteries have in fundraising efforts and would not wish to put that fundraising in jeopardy," the report said.
"The committee encourages the (communications minister) to examine the impact of this bill's amendments ... and how a similar approach might be applied to keno-type lotteries without any unintended adverse outcomes."
Greens senator Sarah Hanson-Young said reviewing lotteries across the next year did not do enough to protect those at risk.
"We do not believe the assessment of lotteries being a relatively low-harm service to be representative of the sector today," she wrote in the report.
"We believe that all lottery products, not just Keno-type lotteries, should be included in the ban on credit and that this should be implemented immediately to avoid unintended consequences."
