Yes, these are Australian Natives from rainforests in Qld & N.S.W., they like a moist soil, but not sure how they'd take being fertilised. Some forms of Syzygium are subject to scale attack.
Your best bet would be to fertilise no more than twice per year with Australian Native fertiliser. Generally speaking though, if natives are planted in types of soil where they naturally grow, they should not need very much fertiliser. Obviously you need to keep up the mulch to simulate the recycling which occurs naturally.
Rainforest plants don't usually need a special Australian plant fertiliser. Any general fertiliser should do, though as Pos says, it may not be necessary. I'd spend the money on a good deep organic mulch instead. They thrive on it. They do grow out of the scale problem. Trish
I agree about the psyllid problem, it affects many lilly pillies. I think you'll find the Syzygium leumanii is okay and in the smaller variety the Cascade is fine. There are probably others that are alright, but a bit of investigation is needed.
