The 10 coins below are arranged in such a way that they form a pyramid.
It is possible to turn this pyramid upside down by moving just 3 coins.
Once you have worked out which coins need to be moved, add the value of those 3 coins (as per the table) together to to give you “X”.
The cache can be located at the following coordinates:
S26° 45.(1918/X)
E153° 0(14.511/X)
It is easy to get disorientated and potentially lost near the final GZ, I recommend you set a waypoint when either parking your geo-mobile or leaving the trail
Good luck and enjoy the hunt!!
