Using an International Driving Permit in Victoria
An international driving permit represents a translation of an overseas driver licence. It has no validity on its own and must accompany a current overseas driver licence.

An international driving permit is only valid if it:

* complies with the UN convention for International Driving Permits, and
* is issued by the country the overseas driver licence is issued in; and
* is accompanied by a current overseas driver licence from the same country the permit was issued in.

As a temporary overseas visitor, if you hold a current driver licence from another country, you are allowed to drive in NSW on your overseas licence as long as:

• You remain a temporary overseas visitor
• Your overseas licence remains current
• You have not been disqualified from driving in NSW or elsewhere and
• You have not had your licence suspended or cancelled or your visiting driver privileges withdrawn.

You are not required to obtain a NSW licence if you comply with these conditions and can continue to prove your genuine visitor status to NSW Police if required.

Note 1: If you are a licence holder from New Zealand, you must obtain a NSW driver licence within three months of residing in NSW or you must stop driving.

Note 2:  Australian citizens who reside overseas and are not permanent residents of Australia are allowed to drive in NSW on a current overseas licence as an international visitor. There is no need to apply for the issue or renewal of a NSW licence.

When driving in NSW you must carry your overseas driver licence. Your licence must be written in English or, if the licence is not in English, you must either carry an English translation or an International Driving Permit.

If you are a temporary overseas visitor and you wish to obtain a NSW licence see Temporary overseas visitors obtaining a NSW licence.
