Within the subtropical zone there are three types of climate: Mediterranean, subtropical humid continental and subtropical.
The Mediterranean climate is characteristic of the south-western Australia, climate of this part of the mainland climate is similar to the European Mediterranean countries - Spain and Southern France. Summers are hot and, as a rule, dry, and winter is warm and humid. Relatively small changes in temperature at the time of the year (January - 23-27 ° C, June - 12-14 ° C), sufficient rainfall (from 600 to 1000 mm).
Subtropical continental climate zone covers the southern, adjacent to the Great Australian Bight of the continent, includes a neighborhood of the city Adelaide and extends a little further to the east, in the western regions of the state New South Wales. The main features of the climate - a small amount of rainfall and the relatively large yearly fluctuations in temperature.
Subtropical humid climate zone includes the entire state Victoria and south-western foothills of the New South Wales. In general, this whole area has a mild climate and significant rainfall (from 500 to 600 mm), mainly in coastal areas (penetration of rainfall decreases inland). In the summer temperatures rise to an average of 20-24 °C, but in winter quite fall - to 8-10 °C.° C
The hot climate and a small and irregular rainfall in most parts of the continent led to the, that almost 60 % its territory devoid of runoff to the ocean and have only sparse network of ephemeral streams. Perhaps, on any other continent is not just a poorly developed network of inland waters, in Australia. The annual flow of all rivers of the continent is just 350 km?.
