OP, as, pointed out you will only be able to obtain a 2 year TDL.
Yes, if applying for car + bike same day you can use one COR and a photocopy.
You can renew your liciences even if expired up to one year.
Same as for the COR you could have one medical certificate + photocopy..
Regards your Oz license I assume you have it with you.
OP, moved your thread to motor forum.
