What's the weather like traveling to Australia in late March and early April? Is it okay to wear short sleeves?

Actually, it's ok, depending on where you're going. If it is Keynes, there is basically no problem with short sleeves and bikinis. The temperature there is relatively constant and hot, and it was still very summer when I went there two days ago. If it's Sydney, it depends on the weather that day. The temperature in Sydney this summer is not too high, so if you go to the seaside, if it is sunny, how to wear it, if it rains, hehe, congratulations. It doesn't rain in Sydney this year, which is shared by other cities.

Generally speaking, you can bring one or two short-sleeved shirts or long-sleeved T-shirts. The coat depends on your own cold resistance. We usually wear coats in June and July here.

If you go to the seaside, remember to wear sunscreen, as long as you are ready to expose all parts, especially around your neck. If you forget to protect yourself from the sun, hehe, it will cover your skin in two hours, and boys are no exception!
