This wasp hatched from a cocoon which formed near a Urabu lugens that was collected from Diddams Close Park on 25 Sep 2022. ( See https://canberra.naturemapr.org/sightings/4445941 )
Hi Birdy, do you still have this wasp? If you could get a clearer photo of the veins on the wing that might help to make sure this is Cotesia rather than another Microgastrine wasp
