Stuck On You Traditional Geocache

Firstly,
The contents must only be magnets. My wife cleaned the fridge of all the old magnets when we moved and purchased a new fridge. The magnets had been lying around in a box for more than a year, so she decided it was time to do something about it... Since she knows how much I like geocaching, she decided to give them to me and told me to make a cache out of them.

Secondly,
The location is very near the place where my wife and I got engaged and I am still "Stuck on her"

Satellite reception will be poor, so this location might be a good spot to start out from:
-34º 5.021
151º 3.364

If you see this tree, then you are extremely close to the cache!

Please only leave magnets in this cache!
