I need to travel overseas within the next week, stay away for 2 weeks, then return back to Australia for about 2 weeks, then travel overseas again for a few more weeks. Both of my destinations require that my passport is valid for 6 months after I plan to depart the foreign country. That requirement will be "just" met for the first destination, but not for the second one, since my passport expires in April.
So, at some stage soon I need to renew my passport. To save the extra cost of express passport processing, I would like to apply for a normal passport renewal. I would like to do this before I leave on the first trip and use my existing passport to travel to the first destination. Hopefully by the time I return, the new passport will be issued and I can use the new passport to visit the second destination.
However, I can't find an answer as to whether I can actually do that. Will my existing passport remain valid while the renewal application is being processed? I assume that once a new passport is issued, the old one will be cancelled, but how would that affect things if this happens while I am overseas?
I'd assume the minute a new passport is issued, the old one becomes invalid. I'd just pay the priority processing fee with the renewal done as soon as you return to Australia between your trips. The priority fee might seem a bargain if you are refused entry on your existing passport. It's a gamble.
