What clothes should I bring to Australia and New Zealand in July?

It's winter in New Zealand, and it's only 2 degrees today. It is not particularly cold. (It varies from person to person. ) Just wear a winter down jacket, and then wear autumn trousers. Australia, see where you have been, some places are very cold, similar to New Zealand, and some places are very warm.

Generally speaking, it is convenient for people who are afraid of the cold to bring some jeans, down jackets, thermal underwear, T-shirts, shirts, shoes and sneakers. Don't take too much, or it will take up too much space.
