The cache is not at the published coordinates.

The desert is a harsh unforgiving place. Here only the strong survives. Day after day the sun brutally torments this barren landscape into submission.
The animals that call this place home are some of the toughest and meanest creatures that can be found on this planet. Here you might spot a Desert Fox, or a Giant Sand Mole, or even a Cape Cobra. They have evolved over many centuries to survive in this hostile land.
The plants you will see here somehow survive against all the odds. Port Jackson and hardened grass patches and an occasional cactus stand their ground where ever they can get a grip in the soft hot sand.
Do you have what it takes to find a cache here? ... But be warned… The cache is tougher than any Desert Fox… It is Mean… It is Evil… It is Nasty… It is probably a Difficulty 6 or 7…
At the published coordinates you will find a container that holds some puzzle pieces. South and East Coordinates for the actual cache are to be found amongst those puzzle pieces. Please do not remove any of them. Every piece has been carefully selected to make this puzzle extremely difficult.
And if you do manage to beat the odds, you might just be rewarded with a few drops of water at a nearby oasis.
…..GOOD LUCK..…
