It depends on if you or your hubby have sponsorship (he will have to, you might not).
One of you will be the primary applicant (likely you).
AU has changed their rules recently that so you need to the points test first at the Immi website, then if you meet the points contact each states (or individual school) to find out sponsorship possibilities.
With your Hubby police transfer happens from time to time, but each state has their own police website that you need to check if they're doing them at this time.
