Application for a certificate of operation (form 504)


Overview

You can use this form to:

  • apply for a certificate of operation
  • apply to make changes to your certificate of operation
  • suspend or revoke (cancel) your certificate of operation.

Do not use this form to renew your certificate of competency.

Do not use this form to renew certificate of operation that was in force within the last two years. Instead, make an application to renew a certificate of operation (form 553).

Do not use this form to try to transfer a certificate of operation as they are not transferable. 

If you are transferring ownership of your vessel, use this form to revoke your certificate of operation or remove a vessel from it. The new owner needs to use this form to apply for, or add the vessel to, their certificate of operation.

How to complete this form

Each vessel related to the certificate must have a unique vessel identifier (UVI) or be exempt, or if you've just applied for a UVI, the reference number for your application.

To apply for a new certificate

You'll need to provide the vessel categories and operation type(s) the vessel will be operating in.

If you're applying in the name of an organisation or registered partnership, you'll need to provide an ABN or ACN.

If you're applying in the name of a trust, you must provide a copy of the relevant pages of the trust deed that identify all current trustees, their names and details. Information about the operation or administration of the trust is not required. Please don't submit an application without this documentation. We cannot process your application without it.

  • add a new vessel
  • add a service category (class) or operation type, such as add '2E - charter operations'
  • remove a service category or operation type

  • update the current certificate holder's details, such as to update the name due to marriage.
