Not anywhere I've been there aren't.
Remove all the chain franchises which only sell their own branded products and those which are restaurants as such or which are Indian, Chinese, Japanese etc and there's far less than there used to be just selling fish & chips.
Where I used to live many years ago you could stand in one spot and there were 2 of them within sight and just down the road was a chicken & chips place. The whole lot are gone now and in their place is a bakery cafe, a noodle take away place, a Mexican food place, a sandwich shop, McDonald's, KFC and Domino's pizza for food meanwhile the convenience store aspect of it is covered by Coles trading 7 days a week and the service station having swapped the workshop for a convenience store open 24/7.
Same in the area I lived immediately before this one. Like a lot of places there were two fish & chip shops, one on each side of the road. One's still there but the other one closed down, sat empty for quite a while, briefly emerged as a cafe and I see it's now an Italian restaurant of sorts.
Same everywhere. The big fast food chains and things like noodles, Mexican etc have grown, service stations have swapped workshops for convenience stores and are open extremely long hours but actual fish & chip shops aren't anywhere near as common as they used to be. They still exist but not as common as they once were.
Anyone who thinks the world will never stop wanting ever increasing amounts of Australia's coal and gas is in much the same position as someone circa 1985 in the fish & chip business who ignored the growth of franchised fast food and convenience stores in my view. Change happens and there's quite a few reasons to think that coal and gas aren't where it's going to be at in 2050.
Nah but most will be where the coal and gas come from....
