Two more pics of this one fish via snorkel in Annan River Helenvale, but also of low quality as was my head-on pic in an earlier submission.
In each image subject is above the most central Barred Grunter (numbers of that more common species appear in each image field and are much easier to locate!)
[A (?) hardyhead fish is also present in lower R field in one image and those were common here too]
