Cambodian visa on arrival treats every Australian child as a separate adult applicant — same $30 USD (~$46 AUD) booth fee, own photo, own e-Arrival Card, named guardian rules. Here is the full 2026 family guide for VoA, including the witnessed-consent-letter rule and why eVisa is the calmer route for Aussie families with kids.

Cambodia treats every Australian traveller — adult or child — as a separate VoA applicant. Each child needs their own passport, their own visa-on-arrival form at the booth, their own passport-size photo, and their own $30 USD (~$46 AUD) cash fee. There is no kids discount, no shared family form, and no waived photo for infants. A family of four pays 4 × $30 USD (~$184 AUD) in USD cash. Children under 18 must travel with their named guardian — one parent or a legal guardian — and if only one parent is travelling, the non-travelling parent should sign a witnessed consent letter to head off any questions from the booth officer. Every child also needs their own 14-field e-Arrival Card inside the 7-day window before flying. The calmer route for Aussie families is the Cambodia eVisa: $80 USD (~$122 AUD) per person all-in, Approved in 3 business days, Delivered as a printable PDF by email, and the family walks straight past the VoA queue at KTI, SAI or KOS.
This guide unpacks all of it: the per-child fee maths, the chemist photo plan, the named-guardian rule, the witnessed consent letter, and the e-Arrival Card per child. If you are still weighing the routes, the eVisa vs visa-on-arrival comparison and the Aussie school-holidays family trip guide are the wider-trip companions to this piece. The Cambodia eVisa Australian guide hub covers cost, documents, and processing time in one canonical write-up.

The dedicated VoA photo-on-arrival walkthrough covers the machine spec, the booth rejection reasons, and the airport-by-airport reliability of the photo machine if you do skip the chemist step. The chemist photo guide covers the Australian branch shortlist and how the Cambodian spec compares to the Australian passport brief.
