20 10 approximate temperature of Australia in July and August

The brothers upstairs are talking nonsense. Australian territory covers an area of 7.6 million square kilometers, which is three quarters of the latitude of China. Crossing the tropical temperate zone and approaching the south cold zone, how can it be possible to directly tell you the specific temperature of a winter from a national perspective?

For example, Brisbane, the capital of Queensland in the north of tropical and south temperate zones, is the third largest city in Australia, with an average temperature of about 25 degrees Celsius, which is most suitable for people to swim and water ski here in winter.

The southernmost Tasmania is cool in summer, with an average temperature of 20℃ and warm in winter, with an average temperature of about 10℃.
