Yeah, the dingos were calling intermittently so I took a short recording. Background sound is the people talking - I recorded the audio at a campground.
Revisiting this and I think now that I was probably wrong earlier after looking at more A. hirsutus/suturalis individuals. In typical A. hirsutus, the elytral apices would be more strongly rounded towards the suture and leave a more or less v-shaped gap when viewed from behind.
