Australia is in the southern hemisphere and the seasons are opposite to those in Europe and North America. There are two climatic zones: the tropical zone (in the north above the Tropic of Capricorn) and the temperate zone. The tropical zone (consisting of 40 per cent of Australia) has two seasons, summer (’wet’) and winter (’dry’), while the temperate zone has all four seasons.

(spring to summer): Warm or hot everywhere, tropical in the north, and warm to hot with mild nights in the south.

(autumn to winter): Northern and central Australia have clear warm days, cool nights; the south has cool days with occasional rain but still plenty of sun. Snow is totally confined to mountainous regions of the southeast.

For further details, including climate statistics, see under individual State entries.

Lightweights during summer months with warmer clothes needed during the cooler winter period throughout most of the southern States. Lightweight cottons and linens all year in the central/northern States with warm clothes only for cooler winter evenings and early mornings. Sunglasses, sunhats and sunblock lotion are recommended year round in the north and during the summer months in the south.

Australia is bounded by the Arafura Sea and Timor Seas to the north, the Coral and Tasman Seas of the South Pacific to the east, the Southern Ocean to the south, and the Indian Ocean to the west. Its coastline covers 36,738km (22,814 miles). Most of the population has settled along the eastern and south-eastern coastal strip. Australia is the smallest continent (and the largest island) in the world. About 40 per cent of the continent is within the tropics and Australia is almost the same size as the mainland of the United States of America. The terrain is extremely varied, ranging from tortured red desert to lush green rainforest. Australia’s beaches and surfing are world-renowned, while the country is also rich in reminders of its mysterious past. These range from prehistoric Aboriginal art to Victorian colonial architecture. The landscape consists mainly of a low plateau mottled with lakes and rivers and skirted with coastal mountain ranges, highest in the east with the Great Dividing Range. There are rainforests in the far northeast (Cape York Peninsula). The southeast is a huge fertile plain. Further to the north lies the enormous Great Barrier Reef, a 2000km (1200 mile) strip of coral that covers a total area of 345,000 sq km. Although Australia is the driest land on Earth, it nevertheless has enormous snowfields the size of Switzerland. There are vast mineral deposits.
