He discovered his double game on Tuesday after finishing the night work. "Do I see things?" he said by receiving the news, according to the statement. "I can not believe it."
He shares the $ 70 million ($ 49.7 million) jackpot with another unregistered player from Tasmania, where Lotto officials accuse players of the city of Hobart of checking their tickets.
But another Australian lottery player this month was not so lucky.
However, due to a time zone conversion error on the website, one had put his bet after the winning numbers had been drawn.
Last Thursday, an Australian court ruled that Mr G was not entitled to any of his potential millions since the terms say that entries are not accepted after a tie "regardless of the wrong deadline shown on the website."
His ticket was transferred to the next day – and did not win.
