Temperatures in Australia and New Zealand
It is not very hot in summer there now, 17-25 degrees. Australia can sometimes reach 30 degrees. Wear short sleeves and shorts. It’s okay to wear a suit with long sleeves. Wear long sleeves when it rains and long sleeves when it gets dark (it’s a bit chilly) but it’s okay to wear short sleeves all the time.
If you feel very hot, find a shady place to hide, where you will feel cool just by standing in the shade.
The ultraviolet rays in New Zealand are very strong, so be sure to use sunscreen, as it can burn you black in one day. (I know two Chinese people who have good eyesight in China and are not nearsighted, but they were burned out by the sun when they arrived there)
You shouldn’t have to pay customs duties when you bring it back to China. I don’t know this very well, but I once bought a watch, which was quite expensive. When I put it on my hand, it went straight away without paying any customs duties.
Hope this helps
I have lived in New Zealand for seven years and have been to Australia several times.
Wish you a happy new year
