NAVAREA X
Coordinated by Australia (Australian Maritime Safety Authority); covers the waters around Australia, from the eastern Indian Ocean to the Coral and Tasman Seas.
NAVAREA X surrounds Australia and reaches north toward Papua New Guinea. The Australian Maritime Safety Authority coordinates it, alongside its national AUSCOAST coastal warnings, which seahazards counts in this area too.
Both the NAVAREA X and AUSCOAST in-force lists are collected directly from AMSA, published under a Creative Commons licence; older warnings come from NGA HYDROPAC relays.
