My experience, talking online, has been that Europeans and North Americans largely agree with you, getting rid of DST would be a sensible thing to do.

Unfortunately in Australia, I see that viewpoint a lot less often. My only guess about the reason: it's become a semi-politicised issue here. The states of Queensland and Western Australia don't use it, while the more populous states of New South Wales and Victoria do use it. And there's a strong cultural sense in those states of "looking down" on Qld & WA; if they do something this way, it must be the wrong way to do it. The joke is, "what's the time difference between Sydney and Brisbane? About 1 hour and 30 years." Whereas in Europe it's universal, and in America it's almost universal on the mainland, apart from a fraction of one state. So there isn't as much of that comparison.

Which is all really frustrating, because all the data is so clear that it's a bad thing. Car crashes, heart attacks, suicides, all go up because of it.
