That's pretty much it. But you do need to have the CAA verifications done again in case there has been any change in your details since your last visit.
This is my recent advice from CASA re ID documents:
For UK pilots:
1. one document needs to be a photo ID - eg drivers licence - while this does not count towards the official ID, it does assist with photo and signature confirmation. it also assists if the applicant includes a certified copy of their UK pilot licence.
2. passport or full birth certificate
3. a verifiable reference from someone who has known the person for more than one year by the name they currently have. The referee can be a CASA delegate, DAME, registered medical practitioner registered in the UK or anyone who is entitled to witness a Australian Commonwealth Statutory Declaration (see our website for the list). If the referee is not a CASA delegate or DAME, the referee has to provide copies of their ID documents - either 2 primary documents or 1 primary and 1 secondary or 2 tertiary.
It CAN be done, but does take time. You may be able to speed up the process by faxing the documents in advance of sthe originals.
