In the Australian bush, be wary when poking your hands into dark places inside caves as you never know what might be dwelling there. For some critters, the cave might offer shelter, or perhaps it's a good place to trap food, but for this cave-dweller the main attraction is the water view.
Follow the faint track into the forest a short way then head left towards a giant red gum. From there it's a scramble down through a gap in the rocks and around to the cave. Be wary of the many cliffs and drop-offs in this area; the cache isn't in a particularly dangerous spot but it's probably not a good one for little kids.
