Well, since you're just getting started in electric, I'd look for a car on here. There are a lot of great deals on some very good cars and a lot of them are "down under".
To start off with:
Xray T1FK05, Tamiya Evo IV or 415MSX, FT TC4, Pro4 or Cyclone or a similar chassis. Find out what cars are most supported by your LHS prior to making a purchase..
IB3800's.. I prefer promatch
LRP QC series, Novak GT7 or GTX
Duratrax Ice charger, best bang for the buck on the market
Novak smart tray or Tekin battery doctor
To start off, if you're running one class with 3 heats and a main, you only need 2 or 3 packs. I would look for most of the stuff on here and you really shouldn't have a problem staying within your budget.
Hope this helps,
