TC Vance
Play with the date on the link above, and you will see that its not really all that uncommon. 1999, saw TC Vance, cross the coast up near Onslow travel inland through the Goldfields and into the Great Australian Bight. From memory, it spent about 3 days in the bight still catagoized as a TC..
Actually, I just put in a date from 1975 till now and there are about 15 that ended south of the Bight with one, TC Harriot well into the Southern Ocean, and one TC Ned crossing the coast of Perth in 1989.
