Welcome to the last of the OZGeomuster GeoArt caches (OZGM)
The GeoArt was created to add an extra element to the Lake Macquarie Geocaching area. We hope you had the opportunity to attend the muster in 2018 and as much fun finding the caches as we had creating them. This cache was placed on behalf of the OZGeomuster.

The cache is not at the posted coordinates. This is a true Letterbox hybrid, please do NOT take the official stamp located within the cache.
Solve the puzzle below to locate the cache.
Isn’t getting mail the best! We at the Oz GeoMuster just love getting old fashioned snail mail. Only problem is that it seems our letters aren’t able to be delivered anymore! All I know some time ago our official letterbox was here, then it seems as if some cheeky cacher took it and moved it elsewhere. Such a shame as our brand new specially designed OZ GeoMuster stamp was locked up inside when they took it. I did have a note pushed under the door a few days later and I didn’t think anything of it at the time, but maybe it’s a clue. Hang on a second I’ll see it I can find it.
38 days, 5 hours, 47 minutes and 42 seconds
175 days, 3 hours, 14 minutes and 31 seconds
If you do happen to find our wayward letterbox could you leave us a message to let us know. Feel free to use our stamp, but make sure you leave it behind. If you have a special cacher stamp we’d love for you to leave us an impression, I feel sure there will be some paper in the letterbox for you to do this.
