Do you know what type of pest is making these black fluffy nests on my orange tree and what’s the best way to control them?
I try to spray with eco oil regularly.

I have researched pests of orange trees and find nothing like this. You can probably remove them with gloved hands if you can reach them easily.
I would seek local help from a plant nursery or a university horticultural department in Australia.
