The smaller inlet to the "upper Left" is Breaky creek itself. This is a good place to do some cast netting etc to get some livies (if that is your thing).
If you travel along the bank on the top side of the map (this is Kingsford Smith Dve) there are some great places to fish straight off the bank or on the pontoons that dot the bank.
Also a little way along the bank on the lower side of breaky creek (this is newstead house/Tenneriffe - the same thing - anywhere off the bank or pontoons.
Basically look for rocky walls or lots of pylons, also around the mouth and corners of breaky creek on the dropping tide. Iknow there a some young lads on this site and others who catch a lot of threadfin, bream and shark all in that area you have shown there.
