I can't stand comments like that. The heat in England is NOT the same as the heat in Australia - I know, I was born there.
Australia has air con in every car and building, for starters, and it's a VERY dry heat. Nothing in England is built to cope with 35 degree heat because we only get it a couple of days a year. Most buildings don't have air conditioning, so workplaces are like heat boxes, houses don't come with air-con as standard and if you're in a flat with no outdoor space, you're buggered.
Australian houses are generally more open plan and are designed to be as cool as possible. English ones are designed to trap the heat because most of the year it's bloody freezing. You really can't compare the two countries in that way. They're both designed differently!
