The passport bio-page scan is the second-most-common Aussie eVisa rejection after the photo — but the easiest to fix. Five rules, five minutes on an iPhone or Android, no flatbed scanner required.

Phone camera in daylight, passport flat on a contrasting surface, BOTH edges of the bio page visible, all text including the MRZ legible, no glare on the laminate. Don't use flash. Don't crop tight — leave a small border. JPEG file under 2 MB, ideally 1500×1000 px or larger. Five minutes on an iPhone or Android usually nails it. About 8% of Aussie eVisa rejections are passport-scan issues (glare, partial cropping, or low resolution) — almost all fix with one retake.
After the passport photo, the bio-page scan is the next-biggest reason an Aussie eVisa application stalls. Roughly 8% of all rejections we see come down to the scan — laminate glare across the face, a corner cropped out, a low-resolution shot that turns the machine-readable zone into a blur. Compared with the 25% rejection rate on photos, that is genuinely small, but it is also the most avoidable mistake on the entire application. Five minutes on a phone in good daylight clears it in one go.
The bio page is the part of your Australian passport that has the photo on it — name, date of birth, passport number, issue and expiry dates, the MRZ (machine-readable zone) along the bottom. That is the page Cambodian Immigration needs to see; not the cover, not the visa-stamp pages, not the back endpaper. Sounds obvious, and the wrong-page mistake still accounts for about 1% of all scan rejections — usually someone scanning the cover by accident, or the inside front page with the embossed coat-of-arms but no biographical detail. The Cambodia eVisa documents required for Australians piece covers the full five-item checklist if you need the wider context. Our official Cambodia eVisa for Australians pulls all the pieces — cost, documents, processing — into one place.
This guide is the same internal playbook we use on the scan-QA desk. The five rules that decide whether a scan passes, a step-by-step phone walkthrough you can run through right now at your kitchen table, the common Aussie mistakes ranked by frequency, and the HEIC-to-JPEG fix iPhone users keep tripping over. A compliant scan is a five-minute job. When you are ready, the application takes about ten minutes online and 3–5 days for approval. The Australian application walkthrough covers the full end-to-end, and the Do Australians need a Cambodia visa explainer is the right starting point if you have not begun yet.
Cambodian Immigration's scan spec is shorter and gentler than the photo spec, but the validator still runs an automated read of every upload before a human looks at it. Five rules cover almost every flag. Get all five right and the scan goes through cleanly.
Rule one: both edges of the bio page must be fully in frame. Top, bottom, binding edge, outer edge — all four visible with a small margin of background around the passport. The most common scan rejection is a corner cropped off, usually the bottom-right where the MRZ ends. Leave a thumb-width of contrasting surface on every side.
Rule two: all text legible, including the MRZ. The machine-readable zone is the two lines of < character codes along the bottom of the bio page. Cambodian Immigration parses that zone to cross-check the name, date of birth, and passport number you typed into the application. Tap to focus on the MRZ before you shoot — modern phone cameras default focus to the centre of the frame, which is the photo on a passport, not the text.

Rule three: no glare on the laminate. The plastic film is glossy by design, and camera flash bounces straight off it into the lens. Avoid flash entirely. Use natural daylight from a side window, not directly overhead. If a bright reflection is still on the page in the preview, tilt the passport a few degrees to push it off to the side.
Rule four: JPEG file, under 2 MB. HEIC from iPhone is rejected at the upload stage. File size caps at 2 MB — a full-resolution phone shot at 10 MB will fail until you compress it. The Photos app on both iOS and Android exports at the right size and format from the share menu.
Rule five: resolution at least 1000×700 pixels, ideally 1500×1000 or larger. Modern phone cameras easily exceed that — a default iPhone or Pixel shot is usually 4000×3000 or higher. The risk is on the other end: if you crop too tight or compress too aggressively, you can land below the threshold. Leave the resolution generous.
The single biggest enemy of a clean scan is laminate glare — the bright reflective patch you see when light bounces off the plastic film into the camera lens. About 3% of all Aussie scan rejections trace to glare alone, the top single cause. The fix is geometry: daylight from a side window is far softer than an overhead ceiling light or desk lamp aimed straight down. If you still see a bright patch on the page in the preview, tilt the passport a few degrees until the reflection moves off entirely. Camera flash is the most reliable way to ruin the shot — switch it off.
Hold the phone parallel to the open passport, directly above it, at about 30 cm. The viewfinder should show the full bio page with a clean margin of contrasting surface visible all the way around — top, bottom, both sides. The most common failure on this rule is the bottom-right corner being just outside the frame, taking the second line of the MRZ with it. If you are not sure, look at the preview and check you can see the page corners on all four sides before you take the shot.
JPEG under 2 MB, at least 1000×700 pixels, ideally 1500×1000 or larger. On iPhone, share the photo through Mail or Files and pick 'Most Compatible' to force a JPEG instead of HEIC, or change the camera setting permanently (covered in the HEIC fix below). On Android, the Photos app exports JPEG by default. If the file is over 2 MB, save it again at 'Medium' quality. Do not crop tight to the page — leave a generous border. The validator handles its own downscale and trim.

This is the routine the scan-QA desk recommends to every Aussie applicant who emails in asking how to do it themselves. Five minutes including the upload, no special equipment, works on any iPhone from the last six years or a modern Android.
Step one — open the camera app and turn off flash. On iPhone, tap the lightning-bolt icon and select 'Off'. On Android, tap the flash icon and switch it off. Auto-flash will fire in a dimly lit room and ruin the scan — you want it forced off, not on auto.
Step two — lay the passport flat on a contrasting surface. The Australian passport is dark navy, so a warm dark wooden desk, a black notebook, or a dark grey kitchen bench gives the validator strong edge contrast. (If your only surface is dark too, reverse the trick: put the passport on a sheet of plain white printer paper.)
Step three — open the passport to the bio page (photo + name + the two lines of < character codes at the bottom). Flatten both pages — push gently on the spine. If the passport is brand new and the spine is stiff, weigh the opposite page down with a small object out of frame.
Step four — position yourself near a window. Side daylight is the goal — mid-morning or mid-afternoon is best, late evening yellows everything. The window should be off to one side of the passport, not directly behind you or directly above the page.
Step five — bracket the camera about 30 cm above the passport, parallel to the page. Hold the phone steady with both hands. Make sure both edges of the bio page are in frame with a small border of surface visible around all four sides. Tap on the MRZ at the bottom of the page to lock focus and exposure on the text, not on the photo or the laminate.
Step six — take two or three shots. Move slightly between them, change the tilt by a few degrees if you saw any glare in the preview. Open the photos and zoom in on the MRZ — if you can read every < character clearly, the shot passes. Pick the sharpest of the takes.
Step seven — export and upload. On iPhone, share through Mail or Files and pick 'Most Compatible' for a JPEG. Android is JPEG by default. If the file is over 2 MB, save at Medium quality. Upload to the application form. Done.

5万件以上のオーストラリア人の旅券生物ページアップロードを分析すると、同じ少数のミスが毎週繰り返されています。朗報は、これらのミスはすべて再撮影で修正できるということです。以下は、私たちが最も頻繁に目にする問題のランキングです。

最新のiPhoneは、JPEGより小さく高品質なHEIC形式で写真を保存することがデフォルトになっています — しかしカンボジア移民局のアップロード検証システムはHEICを受け入れません。永続的な修正は30秒で完了します:設定 > カメラ > フォーマット > デフォルトの「高効率」ではなく「最も互換性あり」を選択します。それ以降、iPhoneで撮影したすべての写真はJPEGとして保存されます。
一回限りの修正はより速いが忘れやすい。HEICでスキャン撮影し、通常通り共有してから、メール、ファイル、またはサードパーティアプリを通じて共有し、エクスポートメニューで「最も互換性あり」または「JPEG」を選択 — または「HEICからJPGへ」などの変換アプリを使って、まずJPEGコピーを保存してください。Androidユーザーは这一问题に直面しません。写真アプリとカメラアプリの両方がJPEGをデフォルトとしています。Android唯一の落とし구는、サイズのためにHEIFまたはWebPで保存するサードパーティカメラアプリです。アップロード前にエクスポート形式を再確認してください。
