I have dual Australian and UK citizenship/passports. I am leaving Australia, travelling to Vietnam, then returning to Australia after 13 days.
I was planning to leave Australia with my Australian passport, enter and leave Vietnam with my UK passport, and then enter Australia with my Australian passport.
To complicate things, I have booked flights under my Australian passport, and according to the travel company we booked it under, changing the passport will incur a fee.
I'd rather not have to pay the fee (as it would make trying to travel visa-free null and void) so I was wondering if my previous entry/exit plan will work?
Or will I need a visa in the end? Thank you
