"I was at work this morning on smoko break and decided to check our ticket," said one of the winners.
"I saw that I had three numbers in a row, so I quickly checked that I had the Powerball number and then went back and checked the rest of the numbers," he said.
"As soon as I saw I had all the numbers on one line I just yelled 'holy ****!' - my boss thought I'd chopped my arm off with a saw."
The couple were regular Lotto players who sometimes played their own numbers and sometimes played with a Dip ticket, and the win couldn't have come at a better time for the couple, who have a young family.
"We've been busting our guts trying to buy our first home," the husband said.
"We just went to the mortgage broker earlier this week to see what they could do to help. But they just couldn't make anything work for us...
"We were absolutely gutted and I just said 'maybe that ship has sailed'."
The couple wanted to be smart about how they managed the money.
"All we know at the moment is that we're going to give the kids a really great Christmas this year."
They will continue working and want to remain anonymous.
