Every Australian child — including infants — needs their own Cambodia visa on arrival under their own passport. There is no shared family VoA application and no kids discount on the booth fee.
The booth fee is the same $30 USD (~$46 AUD) per person regardless of age. A family of four pays 4 × $30 USD (~$184 AUD) in USD cash at the desk, on top of the all-in eVisa alternative of $80 USD (~$122 AUD) per person.
Each child needs their own passport-size photo at the booth. Taking the photos at an Australian chemist before flying (~$15-20 AUD for a set of four) is much calmer than wrangling kids through the airport photo machine.
Children under 18 must travel into Cambodia with their named guardian — one parent or a legal guardian listed on the form. If only one parent is travelling, the non-travelling parent should sign a witnessed consent letter.
Every child also needs their own 14-field e-Arrival Card inside the 7-day window before flying. One card per passport, every time, no family-sharing of cards.
For families, the eVisa is the calmer route — Approved in 3 business days, Delivered as a printable PDF by email, and you skip the airport VoA queue entirely.
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.

Solo parent with one child: 2 × $30 USD = $60 USD (~$92 AUD) at the VoA booth.
Two parents with one child: 3 × $30 USD = $90 USD (~$138 AUD) at the VoA booth.

Photos for each child: the chemist plan before flying
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.
Named guardians and the witnessed consent letter rule
Only one parent is travelling with the child while the other stays in Australia — the non-travelling parent should sign a witnessed consent letter so the booth officer has documentary backing.
Separated or divorced parents where custody is shared and only one parent is on the trip — the other parent's witnessed consent letter is genuinely worth carrying.
Grandparents, aunts, uncles or family friends travelling with the child without either parent — the named legal guardian should sign a witnessed consent letter, and bringing a copy of the child's birth certificate is recommended.
Single-parent families where the other parent is deceased or has no contact — a brief explanatory letter plus the child's birth certificate is enough; nothing further is needed.
Step-parent travelling without the biological parent — treat as the same situation as a non-parent guardian and carry a witnessed consent letter.
One e-Arrival Card per child, no exceptions
The 14-fields walkthrough and the couples-and-family shared-fill workflow cover the field-by-field detail, the QR saving rule, and the order most Aussie families find easiest to work through. Both guides assume one card per person, which is the rule.
Why the eVisa is the calmer route for Aussie families
The Aussie family VoA checklist before flying
Confirm every child has their own current Australian passport with at least 6 months validity after the intended departure date from Cambodia. Renew with the DFAT child-passport service 8 weeks ahead of school-holiday weeks.
Take a passport photo set of four per child at Chemist Warehouse, Priceline or Australia Post — $15-20 AUD per child for the set. Ask for the international 35x45mm size.
Withdraw enough USD cash at an Australian bank for the full family booth fee — for a family of four that is around $120 USD (~$184 AUD), best held in a mix of small clean notes. Crisp, no tears, no marker pen, no folds.
Prepare the witnessed consent letter if only one parent is travelling, or if a non-parent guardian is travelling with the child. One Justice of the Peace appointment covers the whole family.
Pre-fill the VoA paper application per child on the plane — name, passport number, flight number, hotel address, guardian name. Attach one photo per form.
Submit one e-Arrival Card per child inside the 7-day window before flying. Save each QR code to phone wallet or print. 14 fields each, $5 USD (~$7.50 AUD) verified through us per card.
Carry a printed copy of every child's birth certificate in the family envelope if any guardianship complication applies. Plain colour photocopy is fine.
Consider switching to the Cambodia eVisa for the whole family at $80 USD (~$122 AUD) per person — Approved in 3 business days, Delivered as a printable PDF by email, no booth queue with the kids.
Do Australian children pay the same Cambodia VoA fee as adults?
Yes. The Cambodian visa-on-arrival booth charges the same $30 USD (~$46 AUD) per person regardless of age, including infants. There is no kids discount, no half-fee, no waived fee for children under a certain age. A family of four pays 4 × $30 USD (~$184 AUD) in USD cash at the desk. The Cambodia eVisa at $80 USD (~$122 AUD) per person all-in is the calmer alternative for families because it skips the booth queue.
Does every Australian child need their own VoA photo at the booth?
Yes. Every Australian child, including newborns, needs their own physical passport-size photo at the VoA booth — 35x45mm equivalent, plain white background, recent. Take the photos at an Australian chemist before flying for around $15-20 AUD for a set of four prints per child. The on-arrival photo machine is harder for small children because the camera height is fixed for adults.
Can both parents apply for VoA for their child on a single form?
No. Cambodian Immigration does not run a shared family VoA form. Every child submits their own paper application at the booth, signed by the named guardian — one parent or a legal guardian. There is no combined parent-plus-child slip. The form needs the child's own passport number, photo, and the family flight and hotel details.
What if only one parent is travelling with the child to Cambodia?
The non-travelling parent should sign a witnessed consent letter — a plain-English letter naming the child, the trip dates, the travelling parent, and witnessed by a Justice of the Peace or another authorised Australian witness. The Cambodian booth officer can ask for this if the family group looks atypical. Carry two printed copies; the booth may retain one.
Do grandparents or other guardians need extra paperwork for the VoA?
Yes. If a child is travelling with a grandparent, aunt, uncle or family friend rather than a parent, the named legal guardian should sign a witnessed consent letter from both parents, and a colour photocopy of the child's Australian birth certificate is genuinely worth carrying. The booth officer is more likely to ask in this case than in a standard two-parent family setup.
Does every child need their own e-Arrival Card?
Yes. The Cambodian e-Arrival Card is one card per passport, regardless of age. A family of four submits four 14-field cards inside the 7-day window before flying. The fee is $5 USD (~$7.50 AUD) verified through us per card, and each card produces its own QR code that the booth officer scans separately. There is no family-sharing of cards.
Is eVisa or VoA better for an Aussie family with kids?
The eVisa is the calmer route for families. The headline fee is higher at $80 USD (~$122 AUD) per person versus $30 USD (~$46 AUD) at the booth, but the family walks straight past the VoA queue at KTI, SAI or KOS rather than queuing four times with the kids. Approved in 3 business days, Delivered as a printable PDF by email, with Free resubmission if Immigration flags a correction.
What happens if a child VoA photo is rejected at the booth?
The booth officer can refuse a photo that is too dark, blurry, wrong-sized, or non-white-background. The family is sent to the on-arrival photo machine for a retake at $2 USD (~$3 AUD) per attempt, paid in USD cash. The queue resets after the retake. Bringing two chemist photos per child from Australia removes this risk almost entirely — the second print is the spare.
