The final container is located near the creek that flows through the valley here. The creek will flood after heavy rain, so be mindful of the weather. The cache is a larger one, and contains a disposable camera. When you find it, you can take a picure of yourself finding it (or some of the beautiful scenery) and replace the camera. Once it's full I'll get it developed and link to the pictures in the cache description. Doing this is entirely optional, and not necessary to log the cache. If you want to go on more of an adventure, following the path at the creek to the east will lead eventually to the Woronora River, with some interesting scenery on the way (including a beach on the creek). Following to the west will bring you out in Bangor again.
