Snuggled in a press release by Game engine company, Emergent, on the 50 new license deals for their cross-platform engine called Gamebryo is a small mention of Melbourne game developer, Red Tribe. It's always interesting to see what engines local developers choose for their games, some take on the task of building the tools and engine in-house, while others choose popuar middleware solutions like the Unreal engine and Renderware (well, in the past, anyway).
Gamebryo looks like a fairly decent cross platform solution, providing tools and compatibility for the Windows, Xbox 360 (including Live arcade), Wii, and PS3 platforms. Some of the more recent games to use Gambryo include Warhammer Online: Age of Reckoning, Sid Meier's Civilization IV: Colonization, and Fallout 3. More information at Gamasutra!
