VH-ADK was withdrawn from use in 1992. When it was restored in 1993 it was as VH-AIW. The aircraft was named after Robin Miller-Dicks, a nurse who flew herself throughout the Outback administering the polio vaccine to children in remote areas. The vaccine was in lumps of sugar, earning her the nickname Sugarbird Lady among Aboriginal people. Dicks was also a renowned aviator. She tragically died of cancer in 1975 aged just 35. Her father was airline pioneer Horrie MIller, of MacRobertson Miller Airlines fame, and her mother notable author Mary Durack.
