The Fantasy Australia group are, as the name indicates, a group of roleplayers whose D&D game-story is based on a fantastic version of the Australian continent (called Ralis).
At times this can correlate with the normal geography of Australia (location of major towns, general lay of the land), at times it makes use of the creatures and environment of the Pleistocene, at other times it draws from various Aboriginal myths and at other times it simply uses the conventions of fantasy roleplaying games from the last three decades.
Fantasy Australia featured in the second issue of the RPG journal.
The group currently meets in Richmond on Thursday nights. There is a campaign and story mailing list available.
