Oz Lotto representative Bronnie Spencer is looking for the winner who bought from Maroubra’s Pacific Square News Agency, located in Sydney's south (pictured).

UPDATE: The winner finally stepped forward on 21 September, but chose to remain anonymous.

The mystery winner of the September 11 Oz Lotto draw is still walking around with $30 Million (US$21.6M) in their wallet.

David Zou, the owner of Pacific Square News, was thrilled to learn his store sold the winning ticket, but due to the entry not being registered to a player's card, the identity of the ticket holder remains a mystery.

The last big win the store sold was a few years ago, David said. That was a $3.5 million Lucky Lotteries Mega Jackpot winning entry.

Oz Lotto, NSW Lotteries spokesperson Bronnie Spencer said: 'We can't wait to confirm the out-of-this-world prize with our mystery winner.  Just imagine how $30 million might change your life and the lives of your nearest and dearest,' she said.

The eastern Sydney suburbs has had no shortage of winners in the past.

Bondi Beach is popular with both tourists and lottery winners.

This year alone, Bondi has produced two Division One winners, with one of them winning twice in one week. A Bondi resident has struck gold twice in the space of five days, after reinvesting some of his lottery winnings on a second winning ticket.

The 40-year-old got his first win when his system entry took out the guaranteed $1 million division one prize, reported the Sydney Morning Herald.

He won again in a Saturday draw, joining 13 other winners of the division one prize – who raked in almost $1.5 million each.  The total cash the two-time winner has now taken home is $2,478,321.33.

The winning numbers in Oz Lotto's $ 40 million draw 1282 on Tuesday were 6, 4, 36, 23, 2, 30 and 32. The supplementary numbers were 11 and 27.
