Bushrangers Cave is a 10 minute walk down the Zig Zag track from the end of Kanimbla Valley Road. About 400m from the start of the track, you will come to a big sign pointing to "Bush Rangers Cave", there is a small scramble down at this point.
The coordinates are for the mouth of the cave, but you will need to scramble up into the mouth and explore the nooks and crannies to find the cache. The cache is a 2L sistema, with mostly kid orientated swaps, and is hidden in a spot that was safely accesible to both the rather large CO and his 6 year old son.
You will definately need a torch (head lamp if possible), and a hat or even helmet is a good idea
The rock face outside the cave is occasionally used by climbers, and the cave seems to get a bit of use as a camp cave, so please ensure the cache is completely covered by the cammo when you replace it
