Commonwealth act
This law creates a comprehensive national security framework to protect Australia's ports, ships, and offshore facilities (like oil and gas platforms) from terrorism, sabotage, and other unlawful interference. It was passed after the 2001 September 11 attacks and in response to international shipping security requirements.

Security Plans: Most major port operators, ship operators, and offshore facility operators must create detailed written security plans explaining what security measures they will take at three different alert levels (Levels 1, 2, and 3 — think of them like colour-coded threat scales). They must actually follow those plans.
Security Levels: The Government Secretary (a senior public servant) can raise or lower the security alert level for specific ports, ships, or facilities based on the current threat environment. Level 1 is the default (normal operations). Levels 2 and 3 represent increasing threat, requiring escalating security responses.
Ship Certificates: Australian ships that travel internationally must hold an International Ship Security Certificate (ISSC) — essentially a certificate proving the ship meets international security standards. Foreign ships entering Australian waters must also meet equivalent standards.
Security Zones: Authorities can declare special security zones around ports, ships, and offshore platforms. Extra access controls apply in these zones — people, vehicles, and goods may need to be screened (checked for weapons or prohibited items) before entering.
Screening: Similar to airport security, people and goods can be screened (searched) before boarding ships or entering secure port areas. Prohibited items can be banned by the Minister.
Cyber Security: The law also covers cyber security incidents — unauthorised hacking or interference with computer systems that run maritime assets. This reflects modern threats to ships and facilities that rely heavily on digital systems.
Security Directions: In emergencies or when a specific threat is identified, the Secretary can issue security directions — binding orders requiring extra security measures. These can be kept confidential. Failing to follow them is a criminal offence.
Incident Reporting: Operators must report certain security incidents to the government.
Enforcement: Inspectors have broad powers to board ships and inspect facilities. Penalties include significant fines. There is also a demerit points system, enforcement orders, and injunctions (court orders stopping unsafe behaviour).
