The pumice-stone originated from the Havre Seamount, an underwater volcano off the coast of New Zealand. The actions of the tides carried this vast pumice raft 4000 kilometres to blanket the beaches of the Gold and Sunshine coast and there are still pockets on the coast where it remains to this day.
This is one such pocket. Have a go barefoot if your feet need defoliating!
Please only attempt to find this one entering from the beach. I do not encourage crossing the fenced barriers along sand dunes as it causes unnecessary damage to the dunes.
Beach entrance 15 is nearby and the cache is a short stroll from here.
There is a trackable path tag for the FTF - didn't fit in the cache so have a look below it :-)
