A man was oblivious to the fact he had won $4.8 million until he received a life-changing call informing him of the news.
The man, from Docklands in Melbourne's CBD, held the winning ticket in the Set for Life draw on May 1.
The Melburnian, aged in his 50s, will receive his winnings in instalments of $20,000 paid every month for 20 years.
"Wow! Wow! Wow!" he said when discovering he was Australia's newest millionaire, according to the Lott.
"You've got my heart racing now! I was having a chilled day doing nothing, and now this!
The lucky winner told The Lott it would take a while for the news to sink in.
"I've been playing Set for Life for a while now, but I've never really thought in any great detail what I would do if I actually won," the ecstatic winner said.
"I'll carry on for the moment until I figure out what to do with my life! This changes everything."
While the first thing many winners would do is type up a resignation letter, the lucky winner said he would still turn up to work this week.
However, he did ponder the prospect of retiring early.
"This certainly makes it an easy choice when I do it," he said.
The winning numbers in the Set for Life draw 2095 were 29, 23, 6, 3, 39, 31 and 44, with supplementary numbers 12 and 38.
The man was the only division-one winner across Australia.
Man win's $4.8m after redundancy
The latest Set for Life win comes after another man received a $4.8 million windfall in March.
The man, from Bondi in Sydney's east, had been hunting for a job after being made redundant and discovered the news while running errands.
"This is insane! It's unbelievable," he said in a statement from The Lott.
"I could cry.
"I was recently made redundant at work, so the timing couldn't be better.
"This is an absolute game-changer for me."
The man said he would buy a bottle of champagne to celebrate with his wife before considering ditching the job search and retiring.
