AUSCOAST coastal warnings

Recorded as: AUSCOAST

The Australian Maritime Safety Authority's national series of coastal navigational warnings for Australian waters.

National warning services and NAVAREA coordinators collect reports of dangers in their waters — from hydrographic surveys, navies, ports and ships — and broadcast them as numbered navigational warnings, some ocean-wide and some coastal.

What the archive holds

6,382 messages in this archive record AUSCOAST as their authority, issued from 1999-05-15 to 2024-05-11. None of them is in force in the latest lists we collected.

Other accounts for 2,432 of 6,382 recorded messages (38%), the largest warning type group in this selection.

Attributed to NAVAREAs, they fall mostly in NAVAREA XI (12), NAVAREA XIV (6) and NAVAREA XV (6).

Located messages lie in 12 sea areas, most often Coral Sea, Indian Ocean and Bass Strait.

The largest yearly count is 2018, with 422 messages. Collection is incomplete between 2024-05 and 2026-08-17, so those years are not comparable.

They reached this archive through HYDROPAC (6,381) and NAVAREA IV (1).
