@ThylacineAlive Yes, I remembered the name as Chelodina longicollis, but I hadn't seen that species for years, so I did a bit of checking. This species is supposed to have a plain white or yellowish throat, which doesn't fit, but my only photo didn't show enough of the body to have much hope of working out what it might be. Your image will give me more to work on, but I don't know yet if it will be enough.
