Australia is the sixth largest country in the world. It's about the same size as the 48 mainland states of the USA and 50 per cent larger than Europe, but has the lowest population density in the world - only two people per square kilometre. Australia boasts over 7,000 beaches - more than any other nation. Australia produces 95 per cent of the world's precious opals and 99 per cent of black opals. Coober Pedy in South Australia is known as the opal capital of the world. Its population is made up of more than 40 nationalities and, with year-round extremes in temperature, more than 50 per cent of the population live in below-ground 'dugouts'.

Sydney is Australia's oldest city, the economic powerhouse of the nation and the country's capital in everything but name. It's blessed with sun-drenched natural attractions, dizzy skyscrapers, delicious and daring restaurants, superb shopping and friendly folk.Although it's come a long way from its convict beginnings, it still has a rough and ready energy, and offers an invigorating blend of the old and the new, the raw and the refined. While high culture attracts some to the Opera House, gaudy nightlife attracts others to Kings Cross.
