I am residing in USA currently and hold Australian PR. Is there possibility of getting dropbox ( Mail in document) option in Australia. I called customer service but no clarity on that. US Travel docs mentions Country of Residence , but wanted to see if there any chance and they consider PR as residence?
You will need to provide a valid Australian address and PR to send and receive the passport via the mail-in option as they only pick up and deliver there.
You should be eligible for mail-in (or dropbox) to use this option.
