There is a way around it on E3 but also a high chance the consular officer will decline you. Best to get a green card on a H1B. Use E3 as a way in (for Aussies), then transfer to H1B and apply for Green Card IF you believe its worth it. Remember the US government can tax you up to 10 years after you have given your green card back should you want to go home..
