I searched a bit more and I found hobbyking.com which sells RC'a as well. Are they good?
Hobbyking is a distributor in China. They carry both cheap and quality products, they have very competitive pricing, and they ship slower than molasses. Here in the US, it takes close to 3 weeks to get a Hobbyking order (unless you pay outrageous prices for expedited shipping).
As for vehicles, my go-to make is Associated, but I have no idea what the market for vehicles and parts from AE is in Australia. They're one of the oldest and strongest here with tremendous aftermarket support, but that won't help you if they're uncommon down under.
HSP/Exceed/Redcat seem to be very global. They are Chinese; the quality is mediocre to good, depending on model.
Thundertiger is Taiwan, they make most of the current Associated stuff, and are good vehicles.
Traxxas is a big name here, but are overpriced for what they are in my opinion.
No idea what HPI offers over there, but they are good products.
& Losi are good, but again, I don't know how the availability is over there.
Xray is based in Europe, they have quite a few electric models, seem to be high quality.
That's about all I got. I'm not really an electric guy, so recommending specific models is outside of my scope.
