Once a listing’s photos are ready, they still have to actually go live on the portals buyers use — and that upload step trips agents up more often than you’d expect. Here’s what’s genuinely published by the two major Australian portals, and what to do about the parts they don’t spell out.

Domain.com.au: The Actual Published Requirements

Domain is one of the few portals that publishes clear technical specs in its help centre:

• Minimum image dimensions of 800px wide by 600px high — smaller images will not load.
• Files up to 10MB are accepted, though anything over 3MB may upload more slowly.
• Accepted formats are JPG, JPEG, or PNG.
• Up to 100 images can be loaded onto a single listing.

realestate.com.au: No Published Spec — Here’s Why That Matters

Unlike Domain, realestate.com.au does not publish a specific minimum resolution, dimension, aspect ratio, or file size requirement for listing photo uploads in its help documentation. In practice, this means the platform is relying on agents (and their photographers) to supply appropriately high-quality images without a hard technical floor to check against — so there’s no “safe minimum” to aim for. The practical takeaway is simple: don’t upload anything smaller or lower-quality than you’d want a buyer to actually see at full size, because there’s no portal-enforced backstop catching an underwhelming image before it goes live.

Why This Should Be a Non-Issue for Your Listings

A professional real estate photography delivery is produced at resolutions well above any minimum either portal would plausibly require — the real risk isn’t technical rejection, it’s a genuinely low-quality image (a dark phone photo, an oddly cropped shot, a screenshot of another image) making it through simply because no portal is checking for that. If your photos come from a professional shoot, portal technical specs are essentially not something you need to think about at all.

Practical Upload Tips

A few things worth checking regardless of portal: upload the same high-resolution files across every portal your listing appears on rather than a compressed version on one and a full-quality version on another, keep file sizes reasonable so uploads don’t time out on a slow connection, and always preview the listing live after uploading — image order, cropping, or an accidental duplicate is far easier to catch on the live listing than in an upload queue.
