Cambodia eVisa on Mobile: 2026 Step-by-Step iPhone/Android Walkthrough for Australians

Steps 1–3: form fill, photo upload, passport scan

The first half of the mobile application is where most of the work happens. Plan for around eight minutes of active screen time if your passport is in front of you and the photo is already on the phone. Doing this in a quiet spot helps — the small fields are unforgiving of fat thumbs and autocorrect.

Step 1 — Fill the form on your phone keyboard

Open the secure online apply page in Safari (iPhone) or Chrome (Android). Tap into the first field and start typing. Use exactly what is on your Australian passport photo page — full given names, no shortened forms, no missing middle names. Toggle autocorrect off if you can; it loves to "fix" Vietnamese, Cambodian or hyphenated names. Most Aussies finish the typing portion in about five minutes. If you want the full document checklist for what you will be typing in, the documents required guide covers each field.

Step 2 — Upload your photo from the camera roll

When the form asks for a photo, tap the upload field. iPhone will give you Photo Library, Take Photo, or Choose File. Android shows a similar picker. Choose the prepared selfie from your camera roll. If you have not taken one yet, step into good daylight near a plain white wall, hold the phone at arm's length at eye level, neutral expression, no glasses. The full photo spec — 4×6 cm aspect, white background, no shadows, no smile — is in the Cambodia eVisa photo requirements guide. Crop to the 4×6 ratio inside the upload screen if prompted.

Step 3 — Scan your passport bio page with your phone camera

Lay your Australian passport open and flat on a dark, non-reflective surface — a wooden table is ideal, a glass coffee table is not. Stand directly above the bio page so the phone camera is parallel to the passport. Use natural daylight, not flash. Both edges of the page must be visible and in focus, with no fingers in the frame and no glare on the laminate. Take the photo, check the machine-readable zone at the bottom is sharp and readable, then upload it. If it looks even slightly fuzzy, retake — a soft passport scan is the second most common reason for delays after HEIC. The full Cambodia visa for Australia citizens page covers what the visa office is checking on that bio page.

Steps 4–6: review, mobile payment, approval PDF

Now the easy half. You've done the heavy lifting; what's left is double-checking, paying, and saving the approval safely. The whole back half of the mobile flow takes around three minutes plus the three-business-day wait for the visa office to process.

Step 4 — Review every field on the small screen

Scroll back through every field one final time before you pay. Phone screens hide errors that a 27-inch monitor would catch instantly. The two most expensive mistakes are name spelling and passport number — both are uneditable after payment, and both mean a fresh $80 USD application if they are wrong. Pinch-zoom into each field. Read the date of birth slowly. Confirm the passport expiry is at least six months after your arrival date. Smartraveller Cambodia is the official DFAT briefing if you want to sanity-check the entry rules at the same time.

Step 5 — Pay with Apple Pay, Google Pay, or a card

The Cambodia eVisa checkout on mobile accepts Apple Pay (iPhone), Google Pay (Android), and any Visa, Mastercard, AmEx or PayPal account. Apple Pay is by far the fastest — double-tap the side button, Face ID, done in three seconds. Google Pay is nearly as quick once it's set up. If a card declines on the first try, our payment troubleshooting guide covers the most common Aussie bank quirks. The fee is $80 USD (~$122 AUD) all-in for tourist, $90 USD (~$137 AUD) for business — the AUD equivalent shows at checkout so you don't need to do mental maths.

Step 6 — Save the approval PDF to Files or Drive

Within three business days the approval PDF lands in your inbox. Open the email on your phone, tap the attachment, and save it. On iPhone, tap Share > Save to Files and pick a folder you will remember (Documents > Cambodia is a clean home). On Android, tap Save to Drive or Save to Downloads. Then email a copy back to yourself as a belt-and-braces backup. The full processing time picture sits in the Cambodia processing time guide if your file is taking longer than the usual three days.

What NOT to do when applying on your phone

Mobile applications fail in predictable ways. After watching thousands of Australian phone applications come through, the same three traps cause more than half the bounces. Avoid these and your phone-only experience is genuinely smoother than the laptop one — fewer windows to juggle, the camera and the form on the same device, and Apple Pay or Google Pay one tap away. The fails below are all easy to dodge once you know they exist.

• Do not take your passport photo with the camera flash on. Flash burns out skin tones, creates harsh shadows behind the head, and produces glare on glasses or laminated documents. Daylight near a window is always better.
• Do not apply on patchy hotel WiFi. Half-loaded form pages are how partial submissions and double charges happen. If the WiFi drops between the photo upload and the payment screen, you can end up with an orphan reference number and no easy refund path. Apply on home WiFi or a strong cellular signal you trust.
• Do not blow through your cellular cap on a 4-6 MB photo upload. If you are roaming overseas, plug into hotel WiFi for the upload steps even if you started the form on cellular. The same applies to the approval PDF — it lands by email but the inline preview can chew data.
• Do not switch apps mid-form on iOS. iPhone Safari occasionally forgets unsaved form state when it is backgrounded for too long. If you need to step away, save your reference number and come back via the resume link in the receipt email rather than expecting Safari to hold your spot.
• Do not rely on the eVisa on your phone screen at the Cambodian border. The PDF must be printed on A4 — two copies, colour where possible. Hotel printers in Phnom Penh, Siem Reap and Sihanoukville will help if you have not printed before you fly.

Once your phone application is approved and the PDF is saved, the last piece of the picture is which Cambodian airport you're flying into. The Cambodia airports guide walks through the differences between Phnom Penh, Siem Reap and Sihanoukville on arrival.
