Eight people (Tina, Colby, Jerri, Amber, Alicia, Skupin, Kimmi, Varner) have returned, and I'm sure Elisabeth could return if Survivor does anything regarding celebrities. In every season with an Australian returnee, they've made the final episode (Amber in All Stars, Jerri/Colby in HvV, Skupin in Philippines, Kimmi in Cambodia).
