Welcome to Wombat Hole.
The wombats are pretty big in these parts. If you look on google earth you will see other holes such as this dotted around the area. The wombat who dug this hole planted a nice thorny garden to protect it. Take care and navigate your way to the cache carefully.
Thanks to UdderChaos and GoShaz who gave permission to steal the idea from their now archived caches 'Wombat Holes" and 'Wombat Hole".
