Might be possible, but I'm guessing the inspector would need 2 know the rules for your state.
I found this from an article "
MOTORING ENTHUSIASTS’ CONFERENCE EASTERN CREEK"
29. Why won’t NSW recognise and accept engineering certificates issued by other Australian registration authorities?
Under the Commonwealth Mutual Recognition Act 1992 RMS can only accept certificates issued in
another State or Territory if the certificate was issued in accordance with legislation that is reasonably
equivalent to the NSW legislation.
NSW is currently reviewing the potential for certificates from other state s and territories to be recognised by NSW where appropriate.
