Bunjil: Based on recent log/s it would seem this cache has been abandoned.
As the CO did not archive this cache themselves - see the Help Centre article 'Archive a geocache' it has been done for them.
If there are components or remnants of the cache and you haven't already done so, please return to the GZ and collect the cache (or remnants). We don't want to litter our environment with Georubbish.
