Good morning,..
If you intend to drive in Aust for more than three months, you will need to sit for a highway code test at the Motor Vehicles Registry (MVR) Office. This test will be conducted on a PC inside a cubicle in which you will sit by yourself. There is a time limit for your to complete this test, and you will be required to have a number of right answers,.. I can't remember the number here,.. but my wife, and my kids did theirs with one try. I think you are allowed more than one try.
For the on=the=road, you will do the normal drive on the road with the examiner sitting beside you. You can use your own car if you wished to, and you will need to make an appointment with an examiner who will meet you at the MVR Office.
If you are holding an SG Driving Licence, you can convert over into an Aussie Driving Licence without the everything I said above, if your're holding a Msian DL, you'll have to do the above.
Above are quite standard if you intend to drive a normal private passenger car on a highway, but the rules are slightly different if you intend to ride a bike. I'm not too sure of all the rules for a bike,.. need to ask my boy....
Bear in mind if you intend to drive for motorsports, there are other things you will need to fulfill before you can bring your car onto the lapsprint circuit.
Hope my explanations above helps,...
I came over to Sydney in Jan 1981 and converted my driver's license (and motorbike) to a NSW license. In those days you could just convert straight away without sitting for anything. They give you a paper license with no photo on it - this means anyone could use your license. That was Sydney when i first arrived.
I was a student then and went on to buy a motorbike for A$450 (slightly used 100cc Honda) to go to Uni - fell off the bike a couple of times within 3 months and my mom decided that it was too dangerous to ride in Sydney so she bought me a second hand Toyota Corolla (4 years old) from a private seller. Learnt my first lesson living in Sydney from buying this car as the car had been written off and this backyard repairer had done a cheap repair (a lot of things like that was happening in those days) and then sold it to a sucker (like me!!). I paid A$3,200 for the car then and only found out that the car was unroadworthy when i had a minor prang (cost me another A$1900 to have it rectified). Nowadays there still are a lot of these backyard repairers but the law has become a lot stricter now to re-birth a written off car.
