What is the weather like in Sydney in June and July and what clothes should I bring?

It is winter in Sydney at this time, and the temperature should be around 10 degrees. The problem is that the weather in Sydney is a bit close to that of Shanghai. It is cold and cold, so if you are usually afraid of the cold, you can wear a slightly thicker one. A jacket (light down) and a single layer underneath is enough. If the weather is nice, a light jacket will suffice. But if you are going to places with high altitudes such as the Blue Mountains, it is best to bring a knitted sweater as a base layer.
