Cambodia eVisa on a DFAT Second Passport for Australians: Which Passport to Use in 2026

The DFAT second-passport process and timeline (June 2026)

The 6-week lead time is the binding constraint for most first-time second-passport applicants. If you are reading this with a Cambodia trip in 3 weeks and no second passport yet, the second-passport path is not the answer for this trip. The realistic move is to travel on your primary passport for Cambodia, then apply for the second passport ahead of the next frequent-business window. The Australian Passport Office page lists the second-passport application steps and the current fee schedule.

Edge cases — concurrent visas, lost primary, renewal cycles

A DFAT second passport is NOT a substitute for replacing a lost or stolen primary passport. The second is a parallel document for legitimate dual-passport scenarios, not a backup to be activated when the primary goes missing. If your primary is lost or stolen, the correct path is reporting it lost and applying for a replacement primary through the standard DFAT renewal process, even if you happen to hold a second passport at the time. The Cambodia visa lost passport emergency guide walks through the lost-passport sequence in full.

Renewal cycles on the two documents do not move together. The primary is typically a 10-year document, the second a 1-year document. If your second expires while the primary remains current, you simply renew the second through the same DFAT process. If your primary expires while the second remains current, you renew the primary on the standard DFAT renewal path and apply for a fresh eVisa against whichever passport you intend to travel on next. The Cambodia eVisa passport renewal DFAT Australia guide covers the renewal mechanics.

Putting it together before you apply

Pick the passport you will travel on for the Cambodia leg before you do anything else. Open that specific passport, write the number into a note on your phone, and apply for the Cambodia eVisa using that number. Submit the e-Arrival Card later in the 7-day pre-flight window using the same number. Carry that passport in your hand-luggage when you check in at the Australian airport, and present it again at Cambodian Immigration. The matched-pair rule does the rest. The Cambodia eVisa name mismatch fix guide covers the wider name-and-number consistency issues if you are concerned.

If you want the wider eligibility and pathway picture before you commit to the passport choice, the Do Australians Need a Visa for Cambodia explainer covers the eligibility, fee, and pathway picture in full. When you are ready to apply, the Australian application walkthrough takes you through the upload step-by-step.
