Passengers are required to fill out a Customs Declaration before arriving in the country. This declaration also enquires about the importation of natural products such as leather, feathers, food and timber and requires visitors to state whether they have visited a farm prior to travel.

If you intend to stay in Australia and you hold a permanent visa under the Commonwealth Migration Act 1958, you are no longer a visitor. You are allowed to drive or ride in Australia on your current overseas licence for a maximum of three months after arriving in Australia. Since it is a legal requirement that only one licence can be used for driving in Australia, before your Australian licence will be issued, you must present your overseas licence to be made invalid in Australia. If you do not intend to stay in Australia and do not hold a permanent visa, you will be regarded as a visiting driver. If you hold a current overseas driver licence you are not required to get an Australian licence even if your stay is longer than three months.
