No worries mate
If I may...
OK...cleats. Great idea and they work, But, is a fish worth your life?? Just my opinion but I reckon if you need cleats then the fishing spot is not a fishing spot.
I don't remember the name of the hospital (I could use Google but I am lazy:)) near Long Bay Jail. Anyway, there is a golf course there. Walk through the golf course to the rocks. You will see star pickets inserted in the rocks...YES, star pickets!! IDIOTS actually chain themselves to those star pickets so that they don't get swept off.
Life jacket is a very good idea. I use one of those light weight ski jackets. It is like a vest and you don't even notice you are wearing it.
Another thing...and this might sound a bit silly...a helmet. Just about all (or at least most) drownings off rocks, are because the person was hit on the head as they went into the soup. Or should I say their head hit the rocks. A cheap bike helmet will save your life if things go pear shaped. Might look a bit silly, but I don't give a rats what people think I look like. I would rather be in the water swimming than in the water unconscious.
If you wanted to try some spots around North Head or Manly, you will not need cleats (unless you are feeling ambitious). A life jacket (life vest) is a bloody good idea regardless of where you are fishing.
itsaboat mate...Life is just a boat and then ya marry one !
