Where in Australia are you based?? I've seen a bunch of really awesome coworking spaces in Melbourne and can help you get connected to the people I know.
Hey I saw all the videos you mentioned and they look pretty awesome :)
I'll check out Epipheo and CommonCraft they both look great :)
Let me know if you come across or hear of any more.
Thanks Schabes
