One of the 20 people that won a share in last night’s largest Powerball jackpot in history has told 6PR Mornings it was the group's first time playing Lotto after a last-minute decision to have a crack at the record prizemoney.

“Peter”, 54, told host Liam Bartlett and Mornings 'News Review' panel members Gary Adshead and Julie-anne Sprague that winning the $164 million division one jackpot, split across three states, had already "changed lives".

"I couldn't believe it, I checked the ticket about 10 times," he told Bartlett and the panel.

The Goldfields resident, who wants to keep his place of work and where he lives anonymous, said the group had decided "spur of the moment" to put $100 in, with each syndicate member winning $2.7m.

"I thought we'd only won second division."
