I think it's because Australia is surrounded by the sea, and the sea breeze blows inland from all directions, and the sea breeze brings the same climate, so the climate should be the same in places with the same terrain and the same distance from the coastline. Australia, on the other hand, has a large area and flat land, so it produces a variety of climates, and it is distributed in a ring.
But he didn't say it was a semi-ring.

The reason for Australia's arid, ring-shaped climate.
The reason for Australia's arid and annular climate is related to a variety of factors, including geography, atmospheric movements, oceans, and many other factors. First of all, Australia is located south of the equator and is a mid-to-high latitude region. The south is covered by ice and snow in Antarctica, while the north has tropical areas, and the terrain is flattened and disk-shaped, lacking large mountains or high areas of maritime chaos.
This topographic structure makes the Australian Outback very extensive. In addition, most of Australia's land is made up of stony lands such as laterite and loess, which are not conducive to water retention and are prone to gradual loss of water with drought, making them more prone to drought. Secondly, the atmospheric movement zone in which Australia is located is an arid zone.
As the upward movement of the air causes precipitation, while the downward movement of the air inhibits the precipitation. Australia is located in a zone of dried, dried, sluggish air that sinks and does not have much moisture, disrupting potential precipitation conditions and leading to droughts. Finally, Australia's marine environment also has an impact on the climate.
The effects of ocean currents and climate around Australia can lead to changes in ocean surface temperatures, which in turn affect rainfall and air temperatures, leading to climate changes. In summary, Australia's climate aridity and ring shape are related to a variety of factors such as topography, atmospheric movement, and oceanic factors.

If you study geography, you should have an atlas, and if you look at it, I remember that there seems to be ocean currents and the influence of wind belts.

The climate is predominantly tropical. Near the Tropic of Cancer is a tropical desert climate, with a savannah in the outer ring, a tropical rainforest climate in the northeast, a temperate maritime climate and a Mediterranean climate in the southeast corner, and a Mediterranean climate in the southwest corner.
It is distributed in a semi-circular shape.
Australia is located in the southern hemisphere, and although the time difference is only 2-3 hours from China, the seasons are completely opposite. Summer is from December to February, autumn from March to May, winter from June to August, and spring from September to November. The average annual temperature is 27 in the north and 14 in the south.
Australia straddles two climatic zones, with the northern part being tropical, and due to its proximity to the equator, January-February is the typhoon season. Southern Australia is temperate. The central and western regions of Australia are uninhabited deserts, with drought and little rainfall, high temperatures and large temperature differences; In the coastal zone, rainfall is abundant and the climate is humid.

Australia's climate is characterized by its arid or semi-arid climate, which is the driest continent in the world.
Most of Australia, about 70 percent of the country, is arid or semi-arid, with much of the central region uninhabitable. Australia has 11 large deserts, and they cover about 20 of the entire continent. Due to the low rainfall, more than one-third of the continent is actually covered by desert.
Australia is the flattest and driest continent in the world, with dry deserts in the central depression and western plateau.
The average annual rainfall in Australia is 465 mm, and the annual rainfall varies widely and unevenly. The driest region is the Lake Eyre basin, with an average annual rainfall of less than 125 mm. The wettest places are in the north-eastern tropics and south-west Tasmania.
The climate varies greatly across Australia. The northern part of the continent has a humid tropical climate, the east** region and the western coast have a warm and not too hot climate, while the south coast of the continent and Tasmania have cooler climates. Overall, there are warm summers and not-so-cold winters across Australia.
The warmest place on record in Australia was in the north-eastern interior of Crooncari, where temperatures reached as high as 53 in 1889; The coldest place is Charlotte Pass, where in 1994 the lowest temperature recorded in the snow near Mount Corciakos was minus 23. The northern part is tropical, and most of it is temperate. The average annual temperature is 27 in the north and 14 in the south, with drought and little rain in the inland areas, with an annual precipitation of less than 200 mm, and 504-1200 mm in the eastern mountains.
Solar radiation is a fundamental factor in the formation of climatic zones. The distribution of solar radiation on the surface of the earth is mainly determined by the solar altitude angle. The solar altitude angle decreases with the increase of latitude, which not only affects the temperature distribution, but also affects the air pressure, wind system, precipitation and evaporation, so that the earth's climate presents a zonal distribution according to latitude. >>>More
