This tool does not provide a formal risk based exemption. An application must be made in the Maritime Arrivals Reporting System (MARS) for a risk based exemption.
A vessel issued with a risk based exemption from MARS for a particular voyage is not required to manage the relevant ballast water prior to discharge at the intended port.
Any High Risk ballast water MUST be managed prior to discharge at the intended port.
For more information on how to comply with biosecurity requirements for ballast water, including acceptable areas for undertaking ballast water exchange, please refer to the department's Australian Ballast Water Management Requirements.
