I fished today at Mindarie on the ocean side of the rock wall and burlied up a about 20 big fish. They would not take squid, mulie or prawn. I put a ball of burlley on the hook and it got nailed. These fish were big. I had 20lb mono and got smashed every time. Just couldn't stop them. They look sort of like a big skippy but not sure, they had a black v shaped tail. I estimate them to be 10 to 12 lb. Can anyone shed some light on what they could be?
