Definitely agree with you on this one . Came to Australia from the UK 13 years ago . Every place we have rented ( can’t afford to buy at the insane prices ) has been freezing cold in winter and like a sauna in summer. The first place didn’t have any form of heating at all and I remember desperately trying to keep the large open- plan living area warm with a couple of freestanding electric heaters . It was freezing and the ceiling to floor single paned windows all around the house let out any heat we managed to conserve and let in so much heat in the summer the place got like an oven. The houses since haven’t been much better although at least we do have A/C in the living area of our current place . It still gets like an oven / freezing in the ready of the house though… Australia is so far behind the times when it comes to insulation and double glazing yet the house prices are crazy expensive for poor quality. I’ve never been as cold / hot indoors as I have since moving here . Went to visit my son who lives in Norway in November one year and I could walk around his house in a t-shirt it was that well insulated and triple glazed .
