Desert
Situated in the outback of Australia, this region is classified under desert and steppe climates.
While vegetation is scarce, specific microclimates support some small plants, such as robust, spiny grasses (like spinifex and porcupine).
The fauna in these hot and arid deserts comprises small nocturnal predators, such as mourning wheat ears, horned vipers (in hot deserts), and ground squirrels (in cold deserts).
Tropical and subtropical desert climates
Extend over a wide region from Australia's western coastline through the expansive interior down to the southern coast; this, together with the steppe climate, is referred to as the outback or bush.
These areas not only rank among the hottest and driest, but the absence of ground cover and clouds can lead to some of the chilliest nighttime summer temperatures.
Annual rainfall typically does not exceed 10 inches.
During peak summer months, daytime highs often surpass 100°F, with northwestern Australia experiencing extreme heat — recorded temperatures from 100º to 120ºF have lasted for up to 160 consecutive days. In winter, average daytime temperatures fluctuating between 50° and 60°F can drop below freezing at night.
