AuZtralia: TaZmania is a expansion for Martin Wallace's AuZtralia core game, which originally came out in 2018 (see "Busy Autumn").  AuZtralia is a game which is set in the same world as Neil Gaiman’s A Study in Emerald (see"Martin Wallace’s ‘Study in Emerald’ 2E"), and the TaZmania expansion adds a new double-sided map to the game. One side of the map can be surveyed for resources and Old Ones, and the other side can be randomized with the 66 tiles included in the expansion.

This expansion is designed for one or two players, or if played with Revenge of the Old Ones expansion, it can support three players. It requires the core game to play.
