In New South Wales, temporary visitors holding a Chinese driver's license can drive in the state with a valid Chinese driver's license, but they must also carry an English translation of the Chinese driver's license. If you have become a permanent resident of Australia or have obtained a permanent visa and intend to reside in NSW, you can use your Chinese driver's license to drive, but only for up to three months. After that, you need to apply for an NSW driver's license.
