DIsney+ subscription visibility lost with change of country

I recently moved from NZ to Australia and have changed my country in the ITunes store (after having to cancel my Apple one subscription and re-start it)

I had a subscription to Disney+ managed through the store in NZ but this is not visible now since I changed country.

I don't want to cancel the subscription but would like to manage it and see if I can change to charges in AUD.

If I delete my account in Disney+ and open a new account from AU will that solve the problem? The Disney+ site advises I need to cancel the subscription otherwise I will continue to be charged....
