What's the weather like in Australia in August?

Australia (I mean New South Wales and Victoria here, that is, Sydney and Melbourne, which are almost all places that schools usually organize to play) is cold at night, but it is not particularly cold, which is much better than southern China. You can wear it like this, but you'd better wear pantyhose with a pair of long pants under it. You can wear a wool coat on your coat. If you are particularly afraid of the cold, you can wear a thin down jacket, but personally, it is not necessary. Australians dress casually, but casually, so you can wear whatever you want.
