Endless sunbaked horizons, dense tropical rainforests, chilly southern beaches.

Australia's biggest attraction is its natural beauty. The landscape varies from endless sunbaked horizons to dense tropical rainforest to chilly southern beaches. Scattered along the coasts, its cities blend a European enthusiasm for art and food with a laid-back love of sport and the outdoors.

Visitors expecting to see an opera in Sydney one night and meet Crocodile Dundee the next will have to re-think their grasp of geography in this huge country. It is this sheer vastness that gives Australia - and its diverse population - much of its character.

As of March 31, 2007 all passengers flying to and from Australia on international flights will only be permitted to carry small quantities of liquids, gels or aerosols in their cabin or carry-on luggage. Small containers of 100 mls (3.5 fl oz) are permitted and must be sealed in a transparent plastic bag. Details of the new security measures can be found at the Department of Transport website.

Domestic travel is not affected by these regulations.
