Obtain non O-A prior to existing extension ends.

[DrJack54]

Can I apply for an O-A (retirement visa) when back AU even though I have valid current extension and reentry permit?

Thank you for any advice.

No problem to do that. The embassy or consulate would not care that you had a valid extension.

Just be sure the immigration officer uses your visa when entering the country instead of your re-entry permit.

Yes, I did that in April with several months left on my previous Non O-A, I also had a re-entry permit as a back up.
