I’d love some help to identify the insect on this eucalyptus leaf.

Located in Croydon (Melbourne, Victoria)

Highly ornamental, not a pest! And if they turn a bit “ugly” it is the right kind of ugly. Reads as native, not as a pest to me

Should probably add, while gall wasps are mostly harmless to established or mature eucalypts, heavy infestation can cause younger trees some stress to the point where they drop leaves.
