The cache starts walking on water at the listed co-ordinates. You need to find a solitary single number - a clue. Let's call this number X.
In the past X used to be a stainless steel number hanging on a fishing line under the walkway about 4 feet into the ocean. It was a great clue and only a handful of people ever found it. The problem is the clue dissapeared. So given the maintenance upkeep of that plus the difficulty, we have changed how you will locate X... here is the instructions.
Within 10 meters of the listed co-ordinate are 4 markings on the walkway that all start with the letter B and then 2 numbers. Go stand exactly in the middle of all 4 so you are within a few feet of all of them. Then using your compass face South East. You are now facing a marking that is B7X where X is the number you need.
Once you've found the number then go to:
S23 09.868, E150 47.25X
Once there - the cache is waiting for you.
This cache does not require you to go onto any boat, and neither should you do so.
A few years ago when our children were small they took sugar sachets from the cafe and poured the sugar in the water to feed the small fish (hence the cache name). Some fish do eat sugar. (just like humans)
