First international travel, making sure I haven't missed any critical steps
I just got my USA passport today and booked my flight to Auckland and then Melbourne. The website mentioned to make sure I have all the correct documents to which I assumed was only my passport but NZ and Australia both required an ETA so I applied for both.
That got me wondering, outside of my passport, drivers license and now my ETA is there anything else I need with me to travel to Australia and New Zealand?
