Other Notices

  • British Admiralty Notices to Mariners repeat Australian Notices to Mariners for those charts adopted by the UK Hydrographic Office. There is a time delay between the Australian Notice and UK copy.

  • British Admiralty Notices to Mariners remain particularly relevant for users of Australian Sailing Directions, as this is a joint publication by the UKHO and AHO. Other UK publications are relevant in Papua New Guinea and Solomon Islands waters. Within Australian waters, other UK publications largely repeat information contained in AHP20 - Mariners Handbook for Australian Waters.
