Hello Zaphk, it's good to have you with us. I read recently of the warm weather you Aussies are having now: the forecast for the Pilbara area (WA) was 49c.
The people in Coober Pedy (SA) have the answer: most of the motel rooms are underground. The barber who cut my hair had his shop underground also. I remember he had no windows in his shop! lol

PS: Question....has Australia had a "white" Christmas in recent times?
