Victoria's compact size and diversity of landscapes makes it ideal for touring. As well, the major roads between cities and country towns are well signposted and generally of a high standard.
The most important rule for travellers in Australia is that you drive on the left-hand side of the road. You must also wear a seatbelt and have your licence with you when you're driving (you'll be fined if you don't).
A driver's licence from home will suffice for up to three months in Australia, as long as it has photo ID and it's for the same class of vehicle you intend to drive. If you're staying more than three months, you'll need to get a Victorian licence.
In Victoria, the speed limit on the open road rises to 100 km/hr and, in some sections of freeway, 110 km/hr. For more information on licences and Victorian road rules, visit the Vicroads website.
