Australia does accept the FAA certification basis and type certificates.
That does not mean an imported aircraft do not need to have Australian registration marks, data plates, exit signs etc. Australian airworthiness requirements need to be met, they apply to all aircraft.
Your friend could have made the commercial decision to buy a second had aircraft that already has ADSB, TCAS, DFDR installed for several million dollars more, or a lower price one with the knowledge they need to comply with Australian requirements. It the choices one has to make when importing a 15-20 year old aircraft.
If he was shopping for an aircraft to use in Australia he should have known what he is looking for, you don't by a 2 seats sports car for a family of 5.
