For anyone interested, there's a small but regular Australian/nz community playing Quake 3's modification Challenge ProMode Arena (CPMA).
We have a steam group and dedicated servers running. The last month or so has seen several rounds of CTF and smaller game types and we're hoping to keep that going. So if anyone's keen to try some CPMA, or even become a regular, come visit us over at irc: Quakenet #promode.au and Steam: http://steamcommunity.com/groups/CPMAAU
All you need to get started is to download the installer http://www.playmorepromode.org/ along with further guides linked on our steam page
