Looks quite like G. acedesta in Caterpillars, Moths and their Plants of southeastern Australia by Peter McQuillan et al but it is probably not that species. Also similar to 1st instars of Pararguda dasymalla in Moths of Victoria Part 1 CD by Peter Marriott
Nature Mapr goes by AFD where it is still Ichneumenoptera https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/154a3019-fd2a-4315-8970-9615d11e1971#names iNat uses a different list so often has different names.
