Alice joined the Australian Army Reserve and served in the Royal Australian Corps of Signals in the 1980s, which inspired Susan to a career in the Australian Army. During her final years at Oxley High School in Tamworth, Coyle was sponsored under the Australian Defence Force Academy (ADFA) scholarship scheme and joined the Australian Army Reserve herself, serving with the 12th/16th Hunter River Lancers.
