Although you've changed your registration location to Australia, I don't think you can change managed payments from one country to another because of the different verification requirements in other countries. I may be wrong and someone else may know for certain.
eBay may say you'll need to open another eBay account in Australia so then you'll need to register to sell and sign up for managed payments in Australia

It would be a good idea to end your current listings until everything's sorted.
Let us know how you go as it may help others in your situation.
