Well this is rather exciting. A Brisbane craft and design gallery called "Artisan" is holding a steampunk exhibit in October - and it appears to be touring all the eastern Australian states. It includes a number of my favourite Australian steampunk artists, and if you're an Australian Steampunk artist they're still open for submissions. You can find more information at their gallery exhibits site (you'll have to search for it as it's in date order of all their exhibits). They also have a Facebook page to add to your calendar.
