Spent many years on holiday in this area in the past - last about 10 yrs ago. You could catch scoolies up to 2 lb on frozen or fresh sandeel - my best bass (6 lbs) was on frozen mackeral belley strip. I used to fish at low tide, and fish the tide up, letting out line as the tide came in so that you were fishing at distance - took loads of smaller bass like this. Biggest one came at about half tide up at 80 - 90 yrds, and was at the Godrevy end of the bay, just over the red river. You can occasionally find soft back crabs in the rocks, which the bass loved, but for some reason these were not always available. I would say a good venue to fish, but must be done after dark as there is a large Surfer presence. A good Ray venue as well apparently, althiough I never caught any.
Good luck, although info admittedly 10 yrs out of date - I'm sure it still stands today though.
Not as good as it looks unfortunately, hasn't been many bass over mls around the last couple of years. Its popular with mullet types there are loads of smaller thinlips but its tough because of the floating wrack moving in the tide, it really rips through so watch your back or you could be going for a swim.
