Apologies if this has been covered before but I don't want to go back and read through all the old threads.

I will be moving to Melbourne on a 457 Visa and I have noticed that with private health insurance there seems to be a 12 month waiting period on obstetrics. What happens if I happen to be pregnant when I move there?

Along the same lines, what has to happen for an expat from the USA to qualify for permanent resident status and therefore medicare? Is this something that my employer needs to sponsor?

Thanks for your help!
