The lucky winner bought the Saturday Golden Casket ticket at Nextra Valley News and Rosalie McPherson, the news agency's owner, knew it was coming.

It had been almost five years to the date since she had her last big winner, more than $2 million.

"I walked in at quarter to five on Sunday and went to the terminal and thought I'm going to see Nextra Valley News pop up," she said.

"And it did. I couldn't believe it."

She said she was surprised with the size of the winning ticket, with the Saturday lotto usually split between eight winners.

This time there were only two first division winners across Australia, with one of those from Gladstone.

Rosalie said it was bought on a registered card and after speaking to Golden Casket the person hadn't been notified yet.

As for Rosalie, "I just get the glory," she said.

"And Golden Casket champagne and a gold plaque."
