What should I wear to Australia these days during the Spring Festival? How's the temperature?

It's the hottest time in Australia, and places like Melbourne can even reach 40 degrees, so it's best to wear short sleeves inside and cotton-padded jacket outside before boarding the plane, and then you can take it off directly after getting off the plane. If you go swimming, of course, you should bring a bathing suit. Inflation in Australia is very serious now, and everything is expensive.
