The cache is at the posted co-ordinates but to log this cache you must have logged a cache in every Australian state and mainland territory in a calendar year. Eg. Qld, NSW, Victoria, Tasmania, SA, WA, ACT and of course the NT. Please post your eligible caches when you log this find. HOWEVER if you are doing a lap and know that by the time you get home you will have met the requirements for this cache, please feel free to log the cache and post your eligible caches once the challenge is completed. Any log that has not submitted eligible cache list by the 1st of January the following year will be deleted!
We were able to do this in 2014 quite by accident and thought it would be a good challenge cache.
The cache is at the site of the Manbulloo airstrip. There is an interesting sign there telling you the history of the place.
Have fun
