Goodday Ray R, Bloody common names for fish
I have a mate who hates these "common names" as its still hard to ID. He likes the scientific names and this is a great example.
I call them Gold Spot Surgeons, you've found, Spotted Sawtail Surgeonfish and Fish Base calls them Yellowspotted Sawtail.
I'm quite certain they are Prionurus maculatus
Seen them at Winney Bay to.
