Put simply (so as a basic and more to it).

Your Partner gets his Australian passport. You get an ETA.
Both travel to Australia and within 3 months apply for a Partner Visa (820) onshore, after 3 months you are on a Bridging Visa A with full work rights.

You will be eligible for Medicare from application of the 820 acknowledgement.
