I think this is a closer match to Poliorhabda (genus), Wingia group, (Oecophoridae fam.). most probably Poliorhabda auriceps, although there are only relatively few examples from life online (ALA and iNaturakist) to compare this speciment with and it it apparently quite variable in its markings. An excellent photo. However, more shots from a dorsal aspect would have helped identification further. A new species for CNM if confirmed. See I. Common (CSIRO 1994), two photos page 105, Oecopjhorine Genera of Australia, I The Wingia Group (Vol 3, CSIRO, Melbourne).
