It's getting unbearably hot

It's getting so hot that I can't handle going outside at all, but what I don't understand is why Queensland doesn't air conditioned platforms, like so many other countries who get equally or more intense heat and I haven't been to Sydney since I was 8 but I think I did go in some air-conditioned rooms on the platforms. I felt like I was going to faint sitting on the ground at south bank station, panting and dripping sweat like I just got out of a pool.
