Why is the Centre of Australia so dry?
Australia is the second-driest continent in the world, with mean annual rainfall less than 600mm for more than 80 per cent of Australia. Australia is so dry because we sit under the subtropical high-pressure belt, which encourages the air to push down, preventing the lift required for rain.
Is the middle of Australia always desert?
Between about 100,000 and 13,000 years ago, the interior of the Australian land mass was more arid than present. The exception is the south-eastern section of the arid zone, where rivers and lakes in the Darling Basin and Willandra region (New South Wales) were more active during between 55,000 and 15,000 years ago.

Did Australia used to be green?
Since the late 1800s, green and gold have been popularly embraced as Australia’s national sporting colours. In 1984, green and gold were formally recognised as the national colours with widespread community support. Prior to 1984, three colour combinations unofficially represented Australia: red, white and blue.
Why is Australian desert red?
In warmer climates, like Australia, chemical weathering is more common. Chemical weathering occurs when conditions change the materials that make up the rock and soil. As the rust expands, it weakens the rock and helps break it apart. The oxides produced through this process give the ground its reddish hue.

Why is Australia referred to as the island continent?
Although Australia is sometimes called an “island continent,” most geographers consider islands and continents to be separate things. According to Britannica, an island is a mass of land that is both “entirely surrounded by water” and also “smaller than a continent.” By that definition, Australia can’t be an island because it’s already a continent.
