evidence: The circular Cartier Island Marine Park with Cartier Island at its centre is now a Sanctuary Zone. [...] Cartier Island Marine Park lies in the Timor Sea within the Australian external territory of Ashmore and Cartier Islands. It is about 600 kilometres north of Broome, Western Australia. [...] Cartier Island and the surrounding marine area within a 10 kilometre radius was a gazetted Defence Practice Area up to 20 July 2011 and has been used in the past as an air weapons range. Although the site is no longer an active weapons range there is a SUBSTANTIAL RISK that unexploded ordnances remain in the area.
