Sydneysiders are being urged to check their tickets after one lucky person won Powerball’s entire $100m jackpot.

Tonight’s Lotto numbers have been drawn - are you $20 million richer? The numbers in tonight’s draw were 1, 13, 7, 23, 2, 34. The bonus ball was 9 and Powerball was 6. The prize rolled over from $17m after the Lotto Powerball draw failed to be.

For the winners who win more than R250 000, they get referred to the lottery operator, Ithuba, for a payout from the PowerBall draw. Free financial and trauma counselling is given to all winners who win above R50 000, tax-free. Players must be 18 years or older to participate.

One of Australia’s biggest ever lottery prizes is still unclaimed, but new details have emerged to help track down the winner.
