Jawbone

 I finished reading the Jawbone Sanctuary book. It was put out by the Jawbone Care group who are a volunteer group formed in 2008 to help look after things. The sanctury is Victoria's smallest at 30ha and was established in 2002 right adjacent to the rifle range site. It seems that the existance of the rifle range since 1878 meant that humans were banned from that coastal fringe for 110 years. The retirement village snuck in before they thought of making the area a park, otherwise the land  probably would have been included. I want to try a snorkel around there at some stage.

The Jawbone name might come from the shape

 rather than finding bones there
