You will require this certificate if you intend to operate ships that have a gross tonnage of 400 tons or more and are carrying oil as cargo or bunker. It is compulsory to carry a relevant insurance certificate when visiting an Australian port.
This requirement does not apply to oil tankers that are already required to have insurance under the International Convention on Civil Liability for Oil Pollution Damage 1992.
In most instances, the requirements of proof can be met by the carriage of an original or certified copy of a normal Protection and Indemnity (PI) Club Certificate of Entry.
