As a highlight of her swimming career, Fraser held 39 records and won eight Olympic medals for Australia, including four gold. Adding to her popularity in her native country and the British Commonwealth, she captured six
Commonwealth Games gold medals. She dominated the high profile 100 metres freestyle event, holding the record for 15 years from 1 December 1956 to 8 January 1972. It was not until 1972, eight years after Fraser retired, that her 100 m record of 58.9 secs was broken. Several weeks before the
1964 Olympics, Fraser was injured in a car crash that injured a vertebra and resulted in the death of her mother Rose. Her sister and a friend were also travelling in Fraser's car during the accident, but survived. This was a fresh tragedy for Fraser and her family following her older brother's death from leukemia in 1950, and her father's death from cancer in 1960.
1964 Summer Olympics incidents and ban from swimming During the
1964 Summer Olympics in Tokyo, Fraser angered swimming team sponsors and the Australian Swimming Union (ASU) by marching in the opening ceremony against their wishes (it was too close to the competition date), and wearing a swimming costume from the competitor of the sponsor in competition, Fraser later denied having swum the moat to steal the flag, telling
The Times in 1991: "There's no way I would have swum that moat. I was terrified of dirty water and that moat was filthy. There's no way I'd have dipped my toe in it." The Australian Amateur Swimming Association banned Fraser from competitive swimming for 10 years. ==Post-swimming activities==
