Do I need a Certificate of Operation for my commercial vessel?
Most domestic commercial vessels (DCVs) in Australia must hold a Certificate of Operation (CoO) before they operate, unless they are covered by an exemption (for example AMSA Exemption 03, which covers recreational use, certain temporary operations, emergency-services and unpowered barges).
The CoO sets the conditions under which your vessel (or vessels) must operate, including how and where they can be used. Critically, a CoO requires you to maintain a Safety Management System (SMS) that complies with Marine Order 504.
If you operate recreationally, you sit outside the DCV regime and do not need a CoO; your obligations are your state or territory’s safety-equipment and licensing rules instead.
