It's beautiful out there so no hardship!
Yup, into the water. It's fairly deep with not many rocks close in so the tide should take it all out in a week or so I reckon. Casuarina sinks, so they can be fish habitat for a while too.
Got to come and go by boat every day, bit isolated to camp and no fresh water source. They managed to get a chipper barged over and lifted up there for the trees up top, wonder what that cost them!?
Side story, years ago in one of the fortifications (called the Devonshire Redoubt) we found some grafitti, one of my husband's relatives had scrawled his name, he was killed in France in the first world war, must have been on a picnic before they shipped out...
