Document errors are one of the most common and entirely preventable reasons Australian visa applications are delayed, returned, or refused. After reviewing the most frequent lodgement problems, here are the seven mistakes applicants make most often — and exactly how to avoid each one.
1. Files over the 5 MB ImmiAccount limit
ImmiAccount has a strict 5 MB per-file upload limit. High-resolution smartphone scans and multi-page documents routinely exceed this. If your file is too large, ImmiAccount will reject it outright — and you may not realise until you're mid-lodgement.
Fix: scan at 150 DPI rather than 300 DPI, use Document mode (not Photo mode) in your scanning app, and compress any oversized PDFs before lodging. VisaPacks includes a built-in PDF compressor — Ebook quality (150 DPI) is sufficient for almost all visa documents.
2. Missing NAATI-certified translations
Any document not in English must be accompanied by a translation from an NAATI-accredited translator. This includes birth certificates, marriage certificates, police clearances, bank statements, and academic qualifications in another language.
A family member's translation — even if they are a professional translator — is not accepted. The translation must be from an NAATI-accredited translator and must include the translator's name, credentials, and contact details.
3. Uncertified copies when certified copies are required
For some documents — particularly identity documents such as birth certificates and police clearances used in offshore applications — the Department requires certified copies rather than plain photocopies. A certified copy is a photocopy signed and stamped by a Justice of the Peace, notary, or equivalent authority confirming it is a true copy of the original.
4. Passports or documents expiring too soon
Your passport should remain valid well beyond your intended stay, since some visa applications take months or years to be decided — check the specific validity requirement for your visa type rather than assuming a fixed buffer applies universally. If your passport expires during the application process, you'll generally need to provide a new one. Similarly, test results (English proficiency tests, skills assessments) have expiry dates, and must be current at the time relevant to your application — check the current validity window for your specific test and visa type.
5. Forgetting subsequent entrant (family unit) documents
If your spouse, de facto partner, or dependent children are included in your visa application — even if they are not traveling with you initially — their documents must be included. This is an extremely common oversight. The application is not just about the primary applicant; each subsequent entrant (member of the family unit) needs their own set of identity, health, and character documents.
- Passport for each subsequent entrant
- Birth certificates for dependent children
- Marriage certificate (if spouse is included)
- Health examination for each subsequent entrant
- Police clearances for each subsequent entrant over 16
6. Inconsistent or confusing file names
Case officers assess hundreds of applications. Uploading files named IMG_20241023_114512.jpg or Scan (3).pdf makes their job harder and can create delays while they identify what each document is. Use a consistent, descriptive naming convention: 01_Passport_Bio_Data.pdf, 02_Birth_Certificate.pdf.
VisaPacks automatically renames your files to a consistent convention when you export — so your bundle arrives clearly labelled without any manual effort.
7. Submitting an incomplete checklist
The most costly mistake is simply not knowing what's required. Many applicants rely on a single checklist they found online and don't realise it's out of date, covers a different visa stream, or doesn't account for their personal circumstances — employment type, relationship status, whether children are included, country of origin.
VisaPacks builds a personalised checklist based on your specific situation, flags which items are required vs optional, and keeps track of what you've uploaded versus what's still outstanding — so you can see at a glance if your lodgement is complete.
Before lodging, do a final review: check every required item has a file attached, verify file sizes are under 5 MB, confirm all non-English documents have accompanying NAATI translations, and check that your passport and any test results remain valid throughout your application.
Frequently asked questions
Which of these mistakes causes the most application delays?
Missing subsequent entrant documents and submitting an incomplete checklist tend to cause the longest delays, since they often aren't discovered until a case officer specifically requests the missing evidence — which can add months to processing. File size and naming issues, by contrast, are usually caught (and fixable) before or during lodgement.
Can a document mistake alone cause a visa refusal?
Most document mistakes cause delays rather than outright refusal, since case officers can request missing or corrected evidence. However, missing evidence that's central to eligibility — such as relationship evidence for a partner visa or a required skills assessment — can contribute to a refusal if it's never provided, so don't assume every gap will simply be requested later.
