I think this is a MALE Acroceuthes metaxanthana (Tort) which has fluffy white 'shoulders' and on its 'face/head' which can be just glimpsed in this shot. [female is brown with concentric circle markings] See https://bold-au.hobern.net/specimens.php?taxid=365516 https://moths.csiro.au/?s=Acroceuthes+metaxanthana https://inaturalist.ala.org.au/observations?taxon_id=471448
The furthest you can get with this is Perginae. This is one of the Myrtaceae feeding genera which includes Acanthoperga, Antiperga, Paraperga, Perga, Peragrapta, Pseudoperga and Xyloperga.
As there is are no systematic references or diagnostic characteristics of the larvae and with over 50 species within this grouping, it's almost impossible to determine the species, let alone genera in which they belong to.
Do not expect removal will happen. TCCS wrote: "Due to the imperative nature of growing and retaining the tree canopy cover across Canberra, in line with targets set out in Canberra’s Living Infrastructure Plan and the Urban Forest Strategy, our operations teams do not remove healthy trees, irrespective of their status as a pest plant. If identified pest species are seen to be in decline or have died, removals take place, and these species are not actively replanted by our teams." So no account is taken of how invasive a species is.
