Ley was born in Kano, Kano State, Nigeria to English parents. When she was one year old, her family moved to the United Arab Emirates, where her father worked as a British intelligence officer. Ley attended boarding school in England until she was 13, when her family migrated to Australia. Her parents bought a hobby farm in Toowoomba, but quickly sold it due to a crash in beef prices. They then moved to Canberra, where her father worked for the Australian Federal Police. She was educated at Campbell High School, Dickson College, La Trobe University, the University of New South Wales and Charles Sturt University, and has master's degrees in taxation and accountancy. She changed her name from Susan to Sussan due to a belief in numerology. When Ley was 19 she enrolled in flight school and gained her commercial pilot's licence when she was 20. She has been a waitress, cleaner, and trained, but did not complete training, as an air traffic controller. But she was a commercial pilot, and later a farmer and shearer's cook. She met John Ley while aerial stock-mustering in south-west Queensland. They married in 1987, settled on her husband's family farm in north-east Victoria, and had three children before their 2004 divorce. Ley was Director of Technical Training at the Australian Taxation Office in Albury from 1995 to 2001 before entering politics.
