Australians are 150 times more likely to get killed by lightning than win on overseas lottery betting, a form of gambling federal MPs want banned.
Government and opposition MPs have united against synthetic lotteries, in part over concerns they would entice people away from traditional lotteries and the revenue they generate for newsagents, pubs and clubs.
"There is a genuine cause for concern that any increase toward lottery betting will be at the expense of consumers, small businesses and community and other government causes funded by official lotteries," Labor frontbencher Michelle Rowland told parliament on Wednesday.
Legislation to ban so-called synthetic lotteries passed the lower house unopposed on Wednesday and with bipartisan support will get through the Senate.
Lottoland chief executive Luke Brill has said the Gibraltar-based lottery betting company would consider a High Court challenge.
"With 700,000 customers in Australia we're going to continue to fight this," he said.
But Urban Infrastructure Minister Paul Fletcher said the coalition believed lottery betting was a "gambling bridge too far".
"Over $350 million is earned by some 4000 newsagencies and official lottery agents across Australia from sales of traditional lottery products. It is clear a shift away from official lotteries would have a negative impact on small businesses," he said.
Labor backbencher Matt Keogh said while the likes of Powerball offered a one in 76 million chance at a win, it a win was far more unlikely in lottery betting.
"The chance of winning the jackpot prize in an overseas lottery of this nature are minuscule with the odds usually less than one in 250 million," he said comparing it to the one in 1.5 million chance of dying from a lightning strike.
Lottery betting is already banned in South Australia, while the Northern Territory doesn't allow betting on Australian lottery.
