Yes, cars are dirt cheap here, and if you have documents to prove no claim bonus rating one from back home, insurance is cheap (no car theft here), petrol is about 50 cents Australian a litre (depending on exchange rate). Driving is crazy but fun. Speed limits are generally 60kmh in city limits (with 20kmh buffer before speed camera flashes) and 120kmh on highways (with same speed camera buffer). Roads are great, especially if you buy a high performance car here, as you can open up on the 4 lane dead straight, flat highways and see what they can do. Enjoy!
