The cache is a simple200ml clip top container that is located on the same side of the creek as the walking track.
Obviously some of the clever locals have made a pretty cool jumps track on the other side of the creek. Actually, this is one of three that I have found whilst hiking around this area. There is no need to cross the creek, the cache is on the same side as the walking track.
Watch out for snakes. Do not attempt on days of extreme bushfire risk.
