Proceed walking south along the coast (or close to the coast) until a waterway is encountered. It is up to the walker to choose what constitutes a waterway (in heavy rain there are many more potential waterways).
Photograph the waterway (ideally at its mouth to the sea).
Walk up the waterway, recording the route followed. Swimming and boating are also permitted (although not usually adopted).
Follow the line of least resistance. Follow the waterway itself or any nearby route that roughly follows the path of the waterway (define as convenient).
Follow the creek until it disappears. Note this point of disappearance.
No requirement, however, to actually reach the point of disappearance on any given walk. It is permitted to stop and turn around for whatever reason. This reason for turning around must be provided.
Document the waterways encountered in this guidebook.
Walks can be re-experienced and continued.
Solo walks are permitted and encouraged, but not required.
