Early life
McMahon was born in Sydney, the son of Sir William McMahon, a prominent Australian politician, and Lady McMahon (née Sonia Hopkins), an heiress, socialite and fashion icon. His father was a Member of the Australian House of Representatives and a high-ranking minister in the 24-year Liberal Government for many years before Julian's birth; he became the 20th Prime Minister of Australia in March 1971, when Julian was two years old. His mother left their three children in the care of a nanny to be with her husband in Canberra during his Prime Ministership. He has an older sister, Melinda, and a younger sister, Deborah. He is of Irish descent through his father.
In an interview with the Herald Sun in 2018, McMahon discussed his childhood; "My Dad... was born in 1908. That’s a very different time to what it was when he was raising me. He must have gone through a strange misunderstanding of how you were parented in 1908 versus how you parent in 1972; it would have been so conflicting. Also how you be a husband in that period of time would have been different."
McMahon was educated at the private, boys-only, Sydney Grammar School, which his father had attended. As a child he dreamed of being an army cadet and playing rugby. McMahon briefly studied law at the University of Sydney and economics at the University of Wollongong. McMahon found no interest in his studies, and began a modelling career. He became known as a model in various fashion capitals, such as Milan, London, New York City, Rome, and Paris.
