It is illegal to drive without being properly licensed. Before attempting to drive on any road in Australia make sure that you have a proper license and you know the road rules.
This summary of information should be read in conjunction with the Roads and Maritime Services (RMS) website. In particular, see the RMS Guide for International Drivers
If you hold an overseas licence, you are allowed to drive the vehicles covered by your overseas licence in NSW indefinitely, as long as:
As an overseas visiting driver, you must carry your licence with you when driving and be able to prove genuine visitor status to NSW Police, if required. Visas, letters from employers or educational institutions, and statements from consulates or diplomatic offices may be used to establish visitor status.
You should read the Road Users Handbook to learn the current road rules in NSW.
If you're a temporary overseas visitor (i.e. not an Australian citizen and not a permanent resident of Australia), you can apply for a NSW licence if you will be in NSW for more than 3 months.
See the rules for applying for a NSW licence as a temporary overseas visitor.
Temporary Licences will be marked with the one letter code "Q" in the conditions area on the front of the licence, while the accompanying text "Evidence of permanent resident status not provided to the RMS" will appear on the back of the licence.
Note: These licensing rules do not apply to people who have previously been issued a NSW licence, people transferring an Australian interstate licence or New Zealand licence to a NSW licence or to visitors who do not hold an overseas licence applying for a NSW learner licence.
If you hold a learner licence from another state or country, you can continue to learn to drive in NSW. You must always be supervised by the holder of an unrestricted Australian driver licence that is a class C or higher (i.e. other people with learner's licences or P1 or P2 licences cannot supervise you).
You must comply with the conditions that apply to learners in NSW, even if they don't ordinarily apply in your home state or country. You must also comply with all relevant conditions that apply to the licence in your home state or country. See also information on speed limits.
