The orange colour and uninterrupted dark midline perhaps suggest R. lineata? https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/6fa656c8-9370-4e97-9725-8cd480e37694#gallery
Difficult to determine however the pattern is similar to superba from northern NSW. It would be great if the specimen was retained and lodged with ANIC
Wow, just found this. It looks like you caught an undescribed pyrgotid fly in the act of approaching Neorrhina punctatum. This appears to be the same fly I have reared from this host: (https://www.inaturalist.org/observations/253727914) and is to my knowledge the first picture showing the fly in the wild and together with its host.
