Would You Know If This Is Peach Leaf Curl?

Question

2 years ago a plant got infected with what I have been told with Peach leaf curl disease. I have treated with Copper Fungicide, leaf curl spray, white oil, Fungus spray etc. Nothing helped cut the plant down but soon other plants were already infected. I kept on cutting the plants down, sprayed even double amount didn’t help. I notice that some of my neighbours has it to. It isn’t in one practical plant all sort different once. I thought this disease only effected Peach Trees. At this stage I don’t know what to do about it any more and I hope you have a answer. Thank you for your help.

The first two photos do resemble peach leaf curl. But it only affects peaches, nectarines, ornamental peach trees and occasionally almond and apricot trees. Do you have those? It looks more like damage caused by psyllids. I saw some photos in my research that looked just like your photos. There are all different kinds of psyllids and they affect a multitude of plants in Australia. Here is more:
