Exhaust Vent
Most Aussie Dryers are designed to vent into the room their operating in, this goes for Hoover, Simpson, Westinghouse at least. The F&P can be vented, as can the whirlpool, but venting a dryer over here isnt a common practise.
We lived in an apartment where the dryer vented into the bathroom, which had no windows, it gets warm in there but nothing like a sauna. Our dryer now runs in the garage with no venting, and there is no buildup of heat or mold.
In AU in summer, most people hang things outside, so thats probably why its less of a problem
