GammaPiSigma: I regretfully have to announce that the cache is gone.
Had a look this afternoon and it is not in the hidey-hole. Clambered down to below the cliff line to have a scout around and see if it was just tossed away but alas it was nowhere to be found. Very sad as I really thought this would be a secure location considering how much scrambling was involved. C'est Le Vie.
The local bogan tribe must have had a big bonfire in that fire ring in the middle of the fire trail as the coals were still radiating heat when I was next to it today.
A big thank you to all the people who attempted this cache. I hope you enjoyed it.
Cheers,
Michael.
