The cache is a plastic tube 2x30 cm, containing a log and full size pencil. This stretch of river is the muggle capital of WA, but if you pretend to be taking a photo of the city, they will not take any notice.
This cache replaces " On The Shore" which was constantly damaged, whenever there was a very high tide. I don't expect this to be an issue this time.
Although parking is available along The Esplanade , there is often a shortage, especially on weekends.
