I'm guessing, if you're on this forum, then EP 1/10 Off-road.
Keilor and Knox are the two clubs in Melbourne from memory. Apparently Keilor has a great surface, you should be able to do the Coleman Cup, I think that's coming up. If you are into EP on-road, Templestowe Flat Track Racers.
Come up to St Ives, Sydney in September for the State Titles. We are also having a J Concepts bash in October.
You will find this link a good source of information for Aussie racing. If you contact 'Maverick CR' he can give you a link to a calendar with all events on.

Melbs is pretty awesome. Some great bars, and Cafe's. Make sure you get coffee at Journal - Flinders Lane. Some Pasta at Peligrini's - Bourke St near Spring. Cheap Pots of beer, bands at the Espy in St Kilda. Beer Pool and Burger at the Snake Pit Fitzroy St. Breakfast at the European, Spring St. The European has a great late night hangout upstairs called the Supper Club, which is good for a night cap. Gaylords in China Town is good for Indian.
Good luck with the move.
Cheers
