Rainfall in Australia is highly variable, with frequent droughts lasting several seasons. Occasionally a duststorm will blanket a region or even several states and there are reports of the occasional large tornado. Rising levels of salinity and desertification in some areas is ravaging the landscape.

To the visitor from the northern hemisphere, many of Australia's birds will immediately seem familiar - Australian wrens look and act very like northern hemisphere wrens, Australian robins seem to be close relatives of the northern hemisphere robins - but in fact the majority of Australian passerine birds are descended from the ancestors of the crow family, and the close resemblance is misleading: the cause is not genetic relatedness but convergent evolution.

Many Perth residents consider their city to be egalitarian and relaxed, with a relatively large middle class and a suburban lifestyle; however, as with all large cities, Perth does have pockets of extreme wealth and poverty. The population is easy-going and friendly, but can be parochial, especially towards the "Eastern States" which are often viewed with deep, but usually jocular, suspicion. This attitude can be attributed mainly to isolation — reflected in the widely-held belief that Perth is "the world's most isolated capital city".

Sydney is the capital city of the Australian state of New South Wales and Australia's largest and oldest city, founded in 1788.

Today's Australian cuisine is some of the most diverse available anywhere, due to the many cultural influences. Modern Australian cuisine has been heavily influenced by the country's South East Asian neighbours, and by the many waves of immigrants from there, and all parts of the world. Similarly, Greek, Lebanese and Italian influences are common. Fresh produce is readily available and thus used extensively, and the trend (urged by long-term government health initiatives) is towards low-salt, low-fat healthy cookery incorporating lean meat and lightly cooked, colourful, steamed or stir-fried vegetables.
