Cambodia Visas for Australian School Group Trips: Students, Teachers and the Paperwork in 2026

Per-student paperwork — passport, photo, parental consent letter

Every student application needs the same three things — a clean colour scan of the bio page of the student's Australian passport, a compliant passport-style photo, and (for under-18s) a signed parental consent letter. The bio scan and photo are the same standards as any adult Tourist eVisa application; the parental consent letter is the piece that is unique to school group trips and the part where trip organisers most often run into trouble at the last minute.

Passport scan

Each student needs an Australian passport with at least 6 months of validity from the date of arrival in Cambodia, and two blank pages for entry and exit stamps. The standard Aussie school trip is booked 6-9 months out, so passport renewals through DFAT can usually be handled comfortably before the visa application; budget 6 weeks for a standard renewal and use the priority service if you are inside 4 weeks of departure. Children's passports are valid for 5 years (versus 10 for adults), which is the most common reason a Year 11 student's passport has expired since their last family overseas trip.

Photo upload

The student photo follows the same Cambodian eVisa rules as any adult — plain light background, face filling roughly 70 to 80 percent of the frame, no glasses, no hat (unless religious), neutral expression, taken within the last 6 months. For school cohorts, the most reliable pattern is asking each parent to take the photo at home using an iPhone in a doorway with the student facing a plain wall, then uploading via the parent permission portal you collate. The chemist photo route works as well but adds $15-20 AUD per student and tends to slow the cohort down if you have 30 families running it in their own time.

Parental consent letter (under-18s only)

Cambodian Immigration does not formally require a parental consent letter at the application stage, but airlines do check for it at Australian departure for unaccompanied minors travelling with an organisation rather than a parent. The letter should be signed by both parents (or sole legal guardian), name the school, name the trip and its dates, list the lead teacher's name and contact details, and confirm the parents authorise the trip. Carry the original signed letter and a colour scan saved on the student's phone. The Cambodia visa for Australian children and minors guide walks through the full content checklist and includes a template paragraph schools can adapt.

Teachers and parent helpers — their own Tourist eVisa, every time

Every adult on the trip — lead teacher, second teacher, parent helper, accompanying nurse, contracted World Challenge coordinator — needs their own Tourist eVisa at $80 USD (~$122 AUD) all-in. There is no professional accreditation, school registration, or Department of Education waiver that changes this. The Tourist eVisa is the right visa class for a teacher accompanying students as a supervisor, even if the school is paying for the teacher's travel costs, because the teacher's role on the ground is supervisory rather than business-purpose. The funds flow from the school covers the teacher's expenses, not a stipend or payment for work delivered in Cambodia.

The exception is the lead teacher attending a paid academic exchange, signing a sister-school MOU with a Cambodian school, presenting at a Cambodian education conference attached to the trip, or running supplier visits for a school's external provider. That activity falls into the Business eVisa category at $90 USD (~$137 AUD) all-in — meetings, paid work, conferences, sales calls, supplier visits, due-diligence, long stays, sponsored events all sit in that visa class. The lead teacher applies for the Business eVisa for themselves while every other adult on the trip applies for the Tourist eVisa; the students stay on the Tourist eVisa regardless.

Three practical points for teachers and parent helpers. First, apply at the same time as the students rather than treating the adult applications as a separate workstream — the cohort moves more smoothly if every Australian passport scan and photo lands in the same week. Second, carry a brief letter from the school principal on the school's letterhead confirming each adult's supervisory role and the trip's dates; Immigration is unlikely to ask, but the letter is useful for travel-insurance claims if anything goes wrong. Third, the Tourist eVisa is single-entry, so any teacher running a side-trip to Vietnam or Laos mid-trip needs a fresh eVisa for re-entry. The Cambodia Business eVisa walkthrough covers the paid-engagement scenarios in detail.

Timing — when to apply for a 30-student cohort

The Tourist eVisa is valid for 3 months from issue, which gives schools a comfortable window for cohort-scale planning. Most Aussie trip organisers we work with run the visa block in the 8-to-10-week countdown before departure, which leaves time for passport renewals, photo retakes, parental consent letter signing, and the inevitable handful of student passports that turn up with damage or insufficient validity. Apply too early — say 4 months out — and the validity may have lapsed by departure for the slowest student in the cohort. Apply too late and you give up the buffer for the small number of applications that need a resubmission.

Each Tourist eVisa is Approved in 3–5 days and Delivered as a printable PDF by email, which means a cohort of 30 student applications submitted on a Tuesday will have all 30 approved PDFs landing in the trip organiser's inbox by the following Friday. We provide Free resubmission if Immigration flags a correction, which most often means a photo retake for a single student rather than a wholesale issue — the resubmission cycle adds 3–5 days, which the 8-to-10-week buffer absorbs comfortably. Aussie-timezone support is available throughout if anything snags, which matters when 30 parents are following up at once.

Friday application timing is worth thinking about for cohort runs — applications submitted on a Friday afternoon Sydney time will not start processing until the Cambodian Monday, which adds a weekend to the timeline. The Friday application timing guide and the broader when-to-apply guide flight-distance walk through the optimal submission windows in more detail.

e-Arrival Card — parents fill, school collates, never the students

Cambodia requires every air arrival, regardless of age, to submit a 14-field e-Arrival Card within the 7-day window before flight. For a school cohort, this means 30-plus separate e-Arrival Cards filed during the final week before departure. The single most important rule for trip organisers is this — parents fill the e-Arrival Card for each child, not the students themselves. The card includes flight details, accommodation in Cambodia, contact phone numbers, passport details, and personal information that requires parental sign-off. Asking students to fill their own card invariably produces a handful of incorrect entries that need to be rejected and resubmitted before departure.

The standard cohort pattern is the trip organiser circulating the school's hotel address and arrival flight details to every parent at the start of the e-Arrival week, with a clear instruction that parents lodge the card for their child by Wednesday at the latest. The trip organiser then collates the confirmed QR codes by Friday, prints a master sheet for the airport, and saves one digital copy per student. The $20 USD (~$31 AUD) per traveller can be billed back through the trip levy, or parents can pay individually at submission — either pattern works.

The e-Arrival Card 14-fields walkthrough and the e-Arrival when-to-fill-out guide cover the actual field-by-field detail; the e-Arrival rejection fixes guide is the one to bookmark for the week before departure in case a small handful of cards bounce back for resubmission. Each card is Checked end-to-end before it reaches Cambodian Immigration when filed through our verified pipeline.

Pulling it together — one application per person, every time

Cambodia school group trips for Australian cohorts are operationally simple once you accept the one-application-per-person rule. Every student needs their own Tourist eVisa at $80 USD (~$122 AUD) all-in, every teacher and parent helper needs their own Tourist eVisa as well, and the lead teacher attending paid exchange or MOU activity needs the Business eVisa at $90 USD (~$137 AUD) all-in. Apply 8-10 weeks before departure from a single logged-in school office account, collate the parental consent letters for under-18s, distribute the approved PDFs once they land, and coordinate the e-Arrival Cards (parents fill, school collates) in the final week. Each visa is Approved in 3–5 days and Delivered as a printable PDF by email, with Free resubmission if Immigration flags a correction and Aussie-timezone support throughout.
