Sources differ as, according to the Australian Government's GeoScience website, Australia's land cover does change constantly due to weather and land use. Over a period of even one decade, figures will change.
An estimated 44% percent, or over one-third of Australia is made up of sandy or stony arid and semi-arid desert, while another 37% is sparse grassland or scrub. The figures for arid and semi-arid are very different from those given in the source quoted below.
Another source states the Arid and semi-arid zone constitute over 70% of Australia's land area (James, Landsberg & Morton, 1995)

"70% of the country is classified as arid or semi-arid."
Almost 40% of australia is classified as 'arid' however the outback covers almost 70% of the continent and is classified 'semi-arid'. In terms of deserts though, only 20% of Australia is actually covered by a desert.
No. The thorny devil is native to the arid and semi-arid deserts of Australia.
The meaning of semi arid and arid is the same
Australia's landscape is dominated by the Outback, a region of deserts and semi-arid land.
Deserts are arid. There is no such thing as a 'semi-arid' desert. Semi-arid regions are steppes or grasslands.
Arid & Semi-Arid
main characteristics of the vegetation of arid and semi arid regions
The answer to this question is presumably "desert". However, this is not strictly true. According to the Desert Knowledge Australia Fact Sheet, 70% of Australia is classified as desert or semi-arid. However, much of this land is used for grazing beef cattle and sheep, so it is not desert in the truest sense. Other figures state an estimated 44% percent, or over one-third of Australia is made up of sandy or stony arid desert, while another 37% is semi-arid grassland or scrub.
Yes. The mulgara is a tiny mouse-sized marsupial that lives in arid and semi-arid grasslands of northern Australian.
Although it is the second driest continent, Australia would not be considered a desert. Less than half of Australia is desert (around 44%). Altogether, 70% of Australia is arid or semi-arid, but even the semi-arid is quite useable, for the most part. The rest of the landscape is made up of a variety of grasslands, rainforest, bushland, mulga scrub, alpine regions, lakes, rivers, beaches, etc.
There are fewer plants to anchor the soil in arid and semi-arid regions.
