I'm pretty sure the road was closed off not only because the road was no longer needed but also to provide regrowth for the Koala habitat - Hence the Geocache name. Now the road remains a trail.
Because the Geocache is a Micro-Cache it only fits a rolled up log page, a mini pencil, a sharpener and possibly a small swap but not a travelbug. The Cache may also be difficult to access at time due to long grass. The Cache includes a piece of PVC Pipe but the rest of the Cache container is just part of the fun.
Happy Caching!
