Their names have not been released, but the woman checked their ticket on Wednesday morning and was so surprised by the win she kept rechecking the numbers and began pacing the floor.
"My partner had left for work and when I finally got through to him, I asked him to sit down," the woman recalled. "Then I said I've got a full line of numbers on Oz Lotto!"
The woman said they now intend to buy a house for her sister and set up an education fund for her sister's children. Then, after an early retirement, the couple plans to pursue their hobbies and do voluntary work in the local community.
