Visas are required by all Commonwealth nationals. Visitors must declare all food, plant material and animal products on arrival in Australia to ensure they are free of pests and diseases; any items that pose pest and disease risks will be destroyed.
Driving is on the left. Visitors may drive on a national licence for a maximum of three months, although an international driving permit is needed by all those whose official language is not English. Drink-driving is illegal and the wearing of seatbelts is mandatory.
There are good cross-country coach services, although flying is the most common way of travelling around the country. Rail travel is slow and expensive. There is a twice-weekly train service that travels from Sydney to Perth and takes three days. Another service links Adelaide with Perth and runs weekly in each direction; journey time is two nights. Reservations are essential on all longd istance train services.
Urban transport services are good and there are suburban rail networks in the state capitals; Melbourne and Adelaide also have tram systems. Taxis are widely available and are metered.
Prevalent diseases where appropriate precautionary measures are recommended include dengue fever (Queensland), Japanese encephalitis and Ross River virus (Western Australia).
There were 6,381,000 tourist arrivals in 2013.
