There are people that play Dota2 here. I'm not one of them, MOBAs aren't my thing, but you will find games with locals fairly easily. If you're looking to join a team or find a regular play group, try asking on the Steam forums and looking for an appropriate group (casual or hardcore or whatever) on Steam itself. It is a bit harder since Dota2 doesn't have a server browser (or at least didn't in the brief time I played) so finding a "clubhouse" server with regulars isn't an option like it is in TF2 or CS:GO.

Nah mate. We're all busy dodging drop bears and venomous snakes and such.

I'm from Melbourne, there's no drop bears here.

Well, hi from Brisbane. DOTA is on my list but too busy with Elite at the moment. Lucky about the drop bears. They are mean mothers!
