A corporation registered outside of Australia can appoint and use its own in-house counsel (lawyer) to provide the Verification of Identity Statement to the Registrar or Commissioner of Titles, concerning the identity of the corporation's officer executing on behalf of that corporation. The corporation's officer or officers executing on behalf of that corporation must complete the Verification of Identity process, undertaken by an Australian consular officer before the corporation's in-house counsel lawyer completes the Statement to the Registrar or Commissioner of Titles.
If you wish to hire a title agent to do this for you, you can find several companies who charge around $300 to perform this service plus the registration and tax fees. When researching title companies, be sure to verify that they have a valid license to perform the service, and have a physical address (not a PO Box). Beware of companies without an actual business location, using a PO box or worse, misrepresenting a Post Office street address as their office.
Bonus : In addition to the legal ownership documents, Vermont will also send you a license plate for registration and operation on the road.
