Hey mate, I have a holiday house down calalla beach and fish jb quite often, it’s an awesome place. I have a quintrex 610 offshore which I launch off Callala Bay boat ramp and I’ve never had any dramas whether it’s high or low tide yet. If your new to the area it might be wise to have some help with you because the wharf is a little high off the water level even at high tide. Good luck and tight lines!!!
