Tuesday's AUD$ 15 million Oz Lotto Division 1 prize has been scooped by a retired couple from Mawson Lakes, South Australia.
The couple claimed their prize on Wednesday and the wife admitted winning such a large amount of money was taking some getting used to.
"I'm too old for this," she said. "I'm going to need something a bit stronger than a cup of tea to celebrate."
When asked if they had any plans for the money she said they would probably leave it in the bank and live off the interest.
"There might be a bit of a splash, but nothing extravagant. We might take a taxi to the doctor's for a change," she joked.
