Cambodia First Trip from Australia: 2026 Planning Checklist (Pre-Trip → Arrival → Day One)

The final week — print, submit, pack

Once the eVisa lands in your inbox the heavy lifting is done. The final week is small, mechanical tasks in a precise order. Print two A4 colour copies of the eVisa PDF — one for your carry-on, one for your checked bag as backup. Cambodian Immigration officers do not accept the eVisa on a phone screen, even with the QR visible. Aussies who try to show it on a phone get redirected to the manual desk, which adds 20–45 minutes after a long flight.

Seven days before arrival, the e-Arrival Card window opens. This is the form Aussies trip on more than any other piece of Cambodia paperwork. Fourteen fields covering passport, flight, accommodation, customs and a brief health declaration. It is separate from the visa, and approving the visa does nothing for the e-Arrival. Submit it more than 7 days early and you'll be silently rejected; submit it after you land and you'll be forced into the slow paper queue at the kiosk.

Three other small jobs in the final week. Order or withdraw ~$200 USD cash — clean, undamaged notes, mix of $10, $20, and a couple of $50s. USD is the working currency in Cambodia for tourist transactions, and the airport taxi, hotel deposit, and first dinner all want it in hand. Download offline Google Maps for Phnom Penh and Siem Reap before you fly. Charge a small power bank. Our e-Arrival form guide walks every field, the processing time guide explains how the 3-business-day clock works, and the best-time-to-visit Cambodia guide helps you align month choice with the run-up.

At the airport on departure day

Departure day from Sydney, Melbourne, Brisbane, or Perth has one moment that catches first-timers out — the airline check-in conversation. Most Aussies expect to be asked for the eVisa. You won't be — at least not by name. What the gate or check-in agent will absolutely check is your passport validity, and they'll cross-reference it against Cambodian entry rules. If you're under the 6-month threshold, they'll refuse to board you. This is non-negotiable. The airline carries the fine for landing a non-compliant passenger, so they enforce it harder than Immigration does.

What to bring in your wallet on the day: your Australian passport, the two printed copies of your eVisa (one in carry-on, one in checked), the $200 USD cash float in a zipped wallet pocket, your usual debit and credit cards, and a printed screenshot of the e-Arrival QR code. Leave any unnecessary cards at home — Cambodia is a low-fraud destination for tourists, but losing your everyday Australian wallet a week into the trip is the kind of admin nobody wants.

One last check before you board. Open your inbox and confirm two emails are there: the eVisa approval PDF and the e-Arrival QR. Both should be saved offline to your phone (download the PDF, screenshot the QR). Roaming and airport WiFi at Cambodian arrivals are workable but not guaranteed in the immigration hall. If either email is missing, our payment troubleshooting guide covers the resend path before you're in the air.

The first hour in Cambodia

You'll step off the airbridge into a quiet, well-signed arrivals hall at KTI, SAI, or KOS. The flow is short. Walk past duty-free, follow the signs to Immigration, and you'll see two queue groups: e-gates on the left for travellers with eVisa + e-Arrival, manual booths on the right for visa-on-arrival applicants. With both QR codes ready, the e-gate walk-through is typically 2–4 minutes. The kiosk reads your passport chip, cross-references the eVisa, scans the e-Arrival QR, takes a fingerprint and a photo, and prints a stamp slip.

After Immigration, baggage carousel, then customs (which is a green-channel walk for most tourists). Outside the arrivals hall there's a clearly marked taxi rank. Use the official airport taxi desk — not the touts who'll greet you in the hall. From KTI to central Phnom Penh is roughly $15–20 USD ($23–30 AUD) and 25–40 minutes; SAI to central Siem Reap is $10–15 USD ($15–23 AUD) and 15 minutes; KOS to Sihanoukville town is $10 USD ($15 AUD) and 20 minutes.

Before you leave the airport, two things worth doing: pull cash from an ATM and grab a local SIM. ATMs at the three airports dispense USD (not Riel) and charge $3–5 USD ($4.50–7.50 AUD) per withdrawal. Pull $200–300 USD if you didn't bring it from Australia. A 10 GB tourist SIM card at the airport kiosk is $5 USD ($7.50 AUD), valid 30 days, and active before you walk to the taxi rank. Aussie roaming via Telstra/Optus/Vodafone works but at $5–10 AUD/day it's the slow way to do it.

Where not to exchange money: street-side stalls, hotel front desks, and the taxi driver. None of those are scams, but the rates are 5–10% worse than the airport ATM, and most tourist-facing businesses in Cambodia quote in USD directly so you rarely need Riel in significant quantities anyway.

Day one essentials

First night in Cambodia is usually a wash — Sydney-Phnom Penh via Singapore or Bangkok lands late evening, and most Aussies check into the hotel, shower, eat something, and sleep. Day one proper starts the next morning, and there are a handful of small adjustments to make the transition painless.

Hotel WiFi versus SIM data. Hotel WiFi in Phnom Penh and Siem Reap is generally fast and reliable; the $5 USD SIM card is for the moments you're not at the hotel — tuk-tuk rides, restaurant Google Translate moments, and the Grab app. Download Grab before you fly. It works exactly like Uber, accepts a foreign credit card, and is the cleanest way to move around Phnom Penh especially in the evening. Tuk-tuks are the daytime mode — $2–4 USD ($3–6 AUD) for most in-city rides, paid in cash.

Riel versus USD spend. Cambodia is a dual-currency economy. Anything over $1 USD is typically priced and paid in USD; change under $1 USD comes back in Riel (the local currency, roughly 4,000 KHR to $1 USD). You don't need to convert at the airport — your USD float covers you, and any Riel you collect as change is spent on water, coffee, or tuk-tuks. Tap water is not drinkable; bottled water is $0.50 USD ($0.75 AUD) and every hotel provides two free bottles per room per day.

Scam awareness is short and easy for Cambodia. The country is meaningfully safer for tourists than its reputation, and the few scams targeting Aussies are obvious: tuk-tuk drivers offering a 'free tour' that lands at gem shops, fake monks asking for donations, and over-priced beggar-child interactions outside major temples. None of them are dangerous, all of them are easily declined. The Smartraveller advisory is worth a read before you fly — DFAT updates it whenever the regional picture shifts.

Pulling the checklist together

Cambodia is genuinely one of the easiest entries in Southeast Asia for Australian travellers. The eVisa is short and online. The e-Arrival is fiddly but small. The airports are modern. English is everywhere a tourist needs it. The currency is half-USD. The only items that catch first-timers out are passport validity, the 7-day e-Arrival window, and the fact that Cambodian Immigration doesn't accept the visa on a phone.

Run the checklist in order — passport at 4 weeks, eVisa at 2 weeks, e-Arrival at 7 days, USD cash and printed PDF in the carry-on — and your first day in Cambodia ends with a tuk-tuk home from dinner along the Tonle Sap riverfront, not with a manual desk queue at the airport. Tourist eVisa $80 USD (~$122 AUD), verified e-Arrival $5 USD (~$7.50 AUD), and you're set. The Australia country pillar is the deeper background read if you want it.
