Permanent visa holders and New Zealand citizens

If you are an Australian permanent resident or hold a permanent visa under the Commonwealth Migration Act 1958 and you intend to stay in NSW, you are not considered to be a visitor. As such, you are allowed to drive in NSW on a current overseas licence for a maximum of three months after arriving in Australia. If you wish to continue driving, you must obtain a NSW driver licence.

If you are a licence holder from New Zealand (regardless if you are a permanent or temporary resident), you must obtain a NSW driver licence within three months of residing in NSW or you must stop driving.
