Career and marriage to William McMahon

Sonia Hopkins worked as an occupational therapist until 1965, when she married William (better known as Billy) McMahon, an aspiring politician in Sir Robert Menzies' government. She was 32; he was 57. It was the only marriage for both. He became Prime Minister in 1971.

Later that year, Sonia McMahon made world headlines after being photographed at the White House wearing a revealing dress in the company of her husband and United States president Richard Nixon. The white full-length dress featured see-through slits down both sides. The Washington Post described the dress as one of the most talked about items of clothing ever to be worn to the White House. In later years (then Lady McMahon) she spoke to her biographer, commenting that her husband chose the dress and that it had "certainly made an impact".

As a prime ministerial spouse from March 1971 to December 1972, McMahon organised for a nanny to look after the children at the family home in the Sydney suburb of Bellevue Hill, while she lived with her husband at The Lodge, Canberra, attending official duties. In an interview with her biographer, McMahon said: "It was a hard decision. I loved being with Bill and I loved being a mum. But I knew I had to make a decision, and I chose to be with my husband."

William McMahon was knighted in 1977 and she became Lady McMahon, although was often still referred to as simply Sonia McMahon. She became a widow in 1988 and in the ensuing years she continued her philanthropic activities. She became a board member and patron of many charities, including the National Brain Foundation, the Sydney Children's Hospital Foundation, the Australian Cancer Research Foundation, the Microsearch Foundation and Australia's Sudden Infant Death Syndrome association.

Health issues On 22 February 2009, McMahon was seriously injured after slipping on the stairs of a luxury pleasure boat owned by her friend, Paul Ramsay. She was taken to St Vincent's Hospital, Sydney suffering broken ribs, punctured lung and multiple other bone fractures.

Media outlets noted her work in contributing to the community by attending fundraisers for charity and different organisations including being on the board of the Sydney Children's Hospital as well as for her complete loyalty to her husband.
