Maritime security level 1 is in force for each security regulated port, each maritime industry participant and each regulated Australian ship unless the Secretary declares that maritime security level 2 or 3 is in force for the port, participant or ship.
If maritime security level 2 or 3 is in force for a port, that maritime security level is in force for every maritime industry participant and security regulated ship within the port.
The Secretary may also declare that maritime security level 2 or 3 is in force for a regulated foreign ship. A regulated foreign ship may also be directed by its flag state to operate at a higher security level.
Division 3 sets out requirements for notifying maritime security level declarations.
In special circumstances the Secretary is able to give security directions to maritime industry participants, employees of such participants, passengers and persons within the boundaries of a security regulated port. Security directions may include confidentiality requirements.
