You will require this if you intend to operate a 406 MHz distress beacon.
If you purchase a new or a used 406 MHz beacon you must register it with the Australian Maritime Safety Authority (AMSA).
Registration of this type of beacon allows search and rescue organisations to access the registration database and find details of registered vessels, aircraft or vehicles, and details of up to three nominated emergency contacts who may be contacted if a beacon is activated and contact cannot be made.
Analogue EPIRBs and PLBs operating on 121.5 MHz are no longer licensed for use and should not be used or offered for sale.
Please consult the Contact Officer for more information.
