Decided you want an AIS but don't know what an MMSI is or where to get it?  Read on...

All boats equipped with an AIS transceiver (transponder) must have a registered MMSI (Maritime Mobile Service Identity) to ensure they are identified as a unique vessel (Boat names don't work as they are not unique).   VHF radios with DSC (Digital Selective Calling) also utilise a MMSI number.

The MMSI consists of a 9 digital number which is assigned by AMSA (Australian Maritime Safety Authority) after submitting an application form.

You will also need to provide the following information:

Note 3:       Diver Handheld VHF DSC transceivers – marine radio operator qualifications are not required if the radio operator in the diving boat (mother vessel) is qualified. In the case of lone divers not operating from boats, the requirement for a marine radio operator certificate remains.
