eTA Australia Supporting Documents: How to Upload Birth Certificates, Marriage Certificates & Business Letters in 2026

Published: 15 March 2026 | Last updated: 31 August 2026. eTA Australia supporting documents may include a birth certificate, marriage certificate, name change document, or business letter, uploaded via ImmiAccount when the Department of Home Affairs issues a Request for Further Information. Accepted file formats are PDF, JPEG, and PNG, with a maximum file size of 5 MB per file and a minimum scan resolution of 300 DPI. Non-English documents must include a certified English translation from a NAATI-accredited translator or equivalent authority in the applicant’s country. Each document must be uploaded as a separate file, and colour scans are mandatory for documents containing stamps, seals, or photographs.

What Supporting Documents Are Required for an eTA Australia Application?

A valid passport biodata page is always required; other documents are conditionally requested via ImmiAccount after an RFI. The initial application is submitted through the Australian ETA App, and reference forms include Form 1419 and Form 1554. When the Department of Home Affairs issues an RFI by email, applicants must log into ImmiAccount and respond within 28 days. For current requirements, visit the Department of Home Affairs ETA Subclass 601 page.

Document Type When Required Priority
Passport biodata page Always Mandatory
Birth certificate Minors or name discrepancy If requested
Marriage certificate Surname changed by marriage If requested
Business letter Business travel under Subclass 601 Business only

Example: a UK citizen applies via the ETA App using only her passport biodata page. Six weeks later she receives an RFI by email, logs into ImmiAccount, and uploads a clear PDF scan of her unabridged birth certificate with a certified English translation.

Birth Certificates for eTA Applications in 2026

An unabridged birth certificate listing both parents is required for minor applicants or if your passport surname differs from your civil records. eTA Australia supporting documents in this category must be scanned as clear, colour copies of originals at 300 DPI, uploaded as PDF, JPEG, or PNG files under 5 MB. Do not submit notarized copies unless explicitly requested in an RFI; a clear scan of the original is sufficient.

Birth Certificates, Marriage Certificates & Name Change Documents for eTA Australia
  1. Attach a birth certificate for every minor applicant, as each child needs their own Electronic Travel Authority (Subclass 601). Minors require an unabridged birth certificate displaying both parents’ names, plus a parental consent letter if only one parent travels.
  2. Provide eTA Australia supporting documents with certified translations for non-English certificates. Use a NAATI-accredited translator and upload the original and translation as paired files through your ImmiAccount.
  3. If your passport shows a different surname from your birth certificate, attach the birth certificate plus a linking document (marriage certificate or deed poll).

Every traveller, including infants, requires a separate eTA Australia. A parent or guardian applies on behalf of a child through ImmiAccount. eTA Australia supporting documents for minors must include an unabridged birth certificate listing both parents. If only one parent travels, attach a parental consent letter; if a child travels with a third party, include custody documents. Refer to Smartraveller for additional guidance on traveling with children.

Marriage Certificates & Name Change Evidence for eTA Applications

Birth certificates are required for minors or name discrepancies; marriage certificates and deed polls prove identity continuity. An eTA Australia marriage certificate or deed poll upload is required when the surname on the passport differs from the name on the birth certificate. The marriage certificate must match the current surname on the passport. Certified translation is required for non-English certificates; upload both the original-language certificate and the translation as a paired set via ImmiAccount.

Document Type Country Where Valid Certified Translation Needed? Upload Format
Marriage certificate All countries Yes, if non-English PDF/JPEG/PNG
Deed poll UK, Australia, New Zealand Yes, if non-English PDF/JPEG/PNG
Court order All jurisdictions Yes, if non-English PDF/JPEG/PNG
Statutory declaration Some jurisdictions Yes, if non-English PDF/JPEG/PNG

Deed Poll, Court Order & Statutory Declaration: Which Name Change Document Do You Need?

Accepted eTA Australia supporting documents for name changes include deed poll (common in UK, Australia, New Zealand), change of name certificate, court order, and statutory declaration. Country-specific equivalents include the “Änderungsbescheinigung” in Germany or “acte de changement de nom” in France. All must be scanned as clear, colour copies of originals at 300 DPI and uploaded as separate files under 5 MB.

Business Letters for eTA Australia Applications: What to Include

Business letters must include letterhead, ABN/ACN, applicant’s role, travel dates, purpose, sponsorship, and host contact. The letter, dated within 6 months of your application, must state the ABN or ACN of the Australian host and include a financial sponsorship statement. eTA Australia supporting documents in this category apply to Subclass 601 applicants traveling for meetings, conferences, or negotiations.

  • Company letterhead with full name, address, and contact details
  • ABN or ACN if the host is Australian; company registration number if overseas
  • Signatory’s full name and title
  • Applicant’s name, position, and employment duration
  • Specific purpose of the visit
  • Exact travel dates
  • Statement of financial sponsorship
  • Australian host contact person (name, phone, email)

Invitation Letter from an Australian Host vs. Employer Support Letter

An employer support letter verifies employment, purpose, and financial backing. An Australian host invitation letter confirms the business relationship and provides local contact details. Submit both eTA Australia supporting documents when traveling for a specific business event.

How to Prepare and Upload Your Documents: File Format, Size & Quality Rules

Common Document Upload Mistakes & How to Avoid Rejection in 2026

The most common eTA Australia document upload mistakes are poor scan quality, missing certified translations, encrypted PDFs, and submitting fraudulent documents which trigger a Public Interest Criterion 4020 ban of up to 10 years. Under PIC 4020, submitting bogus or altered eTA Australia supporting documents can result in a ban from all Australian visas for up to 3 years (if deception was not intentional) or up to 10 years (if knowingly fraudulent).

Quick Pre-Upload Self-Check:

  • Is each document a separate file?
  • Is the file under 5 MB in PDF, JPEG, or PNG format?
  • Is the scan full-page with no cropping, shadows, or glare?
  • If non-English, is a certified translation attached as a second file?
  • Is the PDF free of passwords and encryption?
  • Are you uploading to ImmiAccount (not the ETA App) if responding to an RFI?
Common Mistake Impact How to Fix It
Poor scan quality (shadows, glare, cropped edges) Document rejected; RFI reissued Use a flat surface with even lighting; scan at 300 DPI
Missing certified translation Application delayed Use a NAATI-accredited translator; upload original and translation as a pair
Wrong file format (e.g., HEIC from iPhone) File not accepted by ImmiAccount Convert to PDF, JPEG, or PNG before uploading
Encrypted or password-protected PDF Upload fails Remove all encryption and passwords before uploading
Combining multiple documents in one file Processing delay or rejection Upload each document as a separate file

FAQ: eTA Australia Supporting Documents, Your Questions Answered

Do I need to upload a birth certificate for an eTA Australia application?

Not always. Required for minors, name discrepancies, or if requested after lodgement. For minors, an unabridged birth certificate listing both parents is required.

Can I upload multiple supporting documents in a single file for eTA Australia?

No. Submit each eTA Australia supporting document as a separate file unless the Department of Home Affairs instructs otherwise in an RFI. Each file must be in PDF, JPEG, or PNG format with a maximum size of 5 MB.

Do I need certified translations for non-English birth or marriage certificates?

Yes. Any document not in English must be accompanied by a certified translation from a NAATI-accredited translator in Australia or an equivalent sworn translator in the applicant’s country. Upload both the original and the certified translation as separate files in a paired set.

What file format and size are accepted for eTA supporting documents?

Accepted formats for eTA Australia supporting documents are PDF (preferred), JPEG/JPG, and PNG. The maximum file size is 5 MB per file. Encrypted or password-protected PDFs are rejected. A minimum scan resolution of 300 DPI is required, with colour scans mandatory for documents containing stamps, seals, or photographs.

Are notarized copies required for eTA Australia supporting documents?

Generally no. A clear scan of the original document is sufficient for eTA Australia supporting documents unless the Department of Home Affairs specifically requests a notarized copy in an RFI. Submit clear, full-page scans with no cropping, shadows, or glare.

How do I prove my surname changed after marriage when applying for eTA Australia?

Upload your marriage certificate as a name change document. If issued in a non-English language, attach a certified NAATI translation.

If the name changed through a different legal process, upload a deed poll, court order, or statutory declaration instead.
