What's the weather like in Sydney in June? What clothes do you need to bring?

It's winter in Sydney at this time, and the problem should be around 10 degrees. The problem is that the weather in Sydney is a little close to that in Shanghai, so if you are usually afraid of cold, you can leave a slightly thicker coat (light down) with a single coat inside. If the weather is fine, a thin coat is enough. But if you want to go to a high altitude place like Blue Mountain, you'd better take a sweater as the base.
