So far this month we have had 3 club dives where we focused on debris.
The great news is that we aren't finding much - less than 4kg and most of that was with one piece of steel. We have found small pieces of plastic & glass, a plastic bottle (with a baby octopus inside), 3 aluminium coke cans, 1 pull tab, 1 McDonalds sundae container, some wire, a piece of string and an old fishing float.
