Can a tenant demand air conditioning be installed into a property that reaches dangerously high levels in Oz?

I just moved into a property, its on the seventh floor, and has floor to ceiling windows, (great view) however, when it was 15 Celsius outside it was 37 Celsius inside! Outside people were wearing coats and inside I was in singlet and undies like it was middle of a heat wave. Imagine when it is Summer! Do I have any rights, or if the owner declines installing air conditioning, I am only left with option to move out? I am told that a portable air con will not do enough, and I don't think we should pay for the owners property to get air con. I am really worried that after a massive move, we will need to get out due to the heat issue. PLEASE HELP!
