The cache is not at the given coordinates. You'll get very wet if you go there!
Here's a Bonus Cache (with the relevant Attribute) for you.
"A bonus cache is a Mystery Cache for which you have to find clues in other caches. Sometimes the coordinates for the bonus cache are in one other cache. In other cases, you gather clues for the final coordinates of the bonus cache from multiple other caches." REF
In this case, you will need to gather the clues from one other cache:
Kaffee Kache Queanbeyan - GCAKPD1
This hide uses the Intercache platform. Hidden within the Intercache, a clue will be revealed. Collect all three clues, and use them in the order revealed.
The difficulty and terrain ratings reflect the overall effort required to complete this cache.
Happy Geocaching!
