ImmiAccount upload limits for partner visa applications

The document count

Two things about that number are worth understanding. First, it is documented as cumulative rather than per-stage: uploads made after lodgement, through the “attach additional documents” function, draw on the same allowance as those made at lodgement. Second, lower figures circulate widely — general ImmiAccount guidance describes caps in the range of thirty to sixty attachments — and those appear to describe other visa streams rather than contradicting the partner visa figure.

One hundred sounds generous until the arithmetic starts. A couple with two years of bank statements, a lease, several utility accounts, a few hundred photographs, travel records, witness statements and identity documents will pass 100 individual files without difficulty. That is the constraint the rest of this guide follows from.

Size and formats

PDF is the format Home Affairs guidance is documented as naming for documents, with JPG and PNG typical for single images such as a passport photo page. The 5MB ceiling is per file and independent of page count — a long text-based PDF can sit well under it, while a short document of high-resolution photograph scans can exceed it.

Files that get rejected

Corroborated across independent troubleshooting sources, several file states are documented as rejected outright:

• Compressed archives such as ZIP files.
• Encrypted or password-protected PDFs.
• Fillable PDF forms with active, unflattened form fields — these are documented as needing to be flattened before upload.
• PDFs with embedded scripting or structural corruption, which are documented as producing validation or processing errors.

The last two catch people out most often, because both are easy to produce accidentally: a government form completed on screen and saved retains its form fields, and PDFs assembled by some tools carry scripting the author never asked for.

Why combining documents is the documented approach

Read together with the 100-document allowance, this is the whole design problem of a partner visa submission. Uploading page by page exhausts the allowance on a fraction of the evidence; combining by category keeps the count manageable and matches the documented instruction. Published preparation guidance describes properly consolidated partner visa applications as commonly needing in the order of thirty to forty files rather than a hundred.

No page-count rule appears in any source reviewed, official or otherwise. The documented constraint on a combined file is its size, not how many pages it contains — which is why consolidation works, provided each combined file stays within the per-file limit.

What this means for assembling evidence

The constraints point consistently in one direction: fewer, well-organised, clearly labelled files, each combining related material, each under the size limit, and none of them in a rejected format or state. That is also the shape published guidance describes as the most usable for whoever reads the application — a document that explains what it contains rather than a numbered file whose contents are a surprise.
