Please don't get a car until you have been here a few weeks. I know you think you want one, but you may find a great place to live near a bus line and realise that actually a car is just an inconvenience. That's what we did - moved with a plan to "see how we go and get a car in a couple of weeks if we need one". That was 11 years ago. Never needed one (and yes, we live in the NT nowhere near an MTR). Plus, second the fact that not only is it really hard to rent a place unless you are here, its also a REALLY bad idea. You have to see these things in real life. Ideally at different times of day to gauge unexpected problems (like parking, noisy neighbours, dogs barking etc etc).
