The ACCC just broke the listings lock-in. Here's the part that still costs sellers

She is 58. She sold the family home she had lived in for 19 years, and before a single buyer walked through the front door, the advertising bill was $4,000.

She did not choose that number. She was not really offered a choice at all. The agency she signed with was contractually required to list every property it handled on the country's dominant portal, and encouraged to buy the upgraded placements that carry the higher fees. The line item arrived as a fact of life, the way a council rate does.

This week that arrangement changed. On Monday the Australian Competition and Consumer Commission announced it had accepted an enforceable undertaking from REA Group, the News Corp-controlled owner of realestate.com.au, requiring it to strip restrictive provisions out of its contracts with real estate agencies. The regulator had been concerned those contracts contained anti-competitive restrictions — including clauses requiring all properties to be listed on realestate.com.au — and that this limited the ability of rival services to compete. REA acknowledged the ACCC's concerns and has committed to changes for three years.

"This is a win for competition in the real estate listing market and is expected to enable real estate agents to offer their vendor or landlord clients the listing service that best meets their property advertising needs," ACCC chair Gina Cass-Gottlieb said.

It is a win. It is also a long time coming: the regulator flagged the investigation in May 2025, and it took more than a year to finalise. In 2024, a Guardian Australia investigation reported that agents believed REA was using its effective monopoly to price gouge, and that the cost of listing on the major portals had risen about 30% in three years, with a top-tier listing in inner-city Sydney or Melbourne reaching up to $4,000 on each platform.

The question

So here is the question worth asking, now that the clause is gone.

If a seller was overpaying to advertise her home because one company had written itself into every contract in the market — what else is she accepting as a fact of life simply because the dominant platform presents it that way?

The answer, with numbers

The advertising fee is the visible cost. It is not the expensive one.

Consider what the $4,000 actually bought her: a position in a search result, in a suburb, sorted by price. The portal's job is to sell attention. It is not to tell her whether her street is the strong half of that suburb or the weak half — and the gap between those two halves is where the real money sits.

Work at the suburb level and a median tells you almost nothing useful. Inside a single postcode we routinely see two streets a short walk apart where one carries a sustained rental premium and the other does not, where one clears in under 30 days and the other sits for twice that, where one has three approved developments feeding competing stock into its exit market and the other has none. Same suburb. Same portal search result. Same headline median. Completely different asset.

That is the data the listing fee does not buy. Achieved rent rather than advertised rent. Street-level vacancy rather than a council-wide average. Days on market for that street's stock type. Approved-but-unbuilt supply that will compete with the property on the way out. Buyer depth — how many genuine purchasers exist for that exact property at that exact price point when it is time to sell. Our R-Score and street heatmaps exist precisely because the portal-level view flattens all of it into one number.

A seller who understood her street's actual position could have priced with confidence, chosen her campaign length on evidence, and quite possibly skipped the premium placement entirely. A buyer using the same data does not overpay for a weak street inside a strong suburb because the search result put them side by side.

What it means for you

The ACCC's undertaking does one thing well: it restores choice about where a property is advertised. Agents now have genuine flexibility in how they serve vendors and landlords, and over three years that should apply real downward pressure on listing costs. If you are selling, ask your agent directly what the new arrangement means for your advertising schedule — that conversation is now available to you, and it was not available to her.

But do not mistake a cheaper listing for a better decision. The lock-in that cost her $4,000 was an advertising problem. The lock-in that costs most people far more is informational: accepting a suburb median as the truth about a specific address, because the platform that dominates the search never offered anything more granular.

Falling headline prices make this sharper, not softer. When a market broadly softens, the difference between streets widens — the well-located, supply-constrained street holds while the oversupplied one two blocks over gives up years of growth. National commentary cannot see that distinction. A portal search cannot see it either.

The reframe

This is why property remains one of the most reliable wealth-building assets in the country, and why the people who do badly at it are almost never the people who paid too much for advertising. They are the people who bought the right suburb and the wrong street.

The headline is the noise. The right asset, on the right street, verified with data that goes below the suburb line, is the signal. That has not changed because a regulator improved a contract — if anything, it matters more now that everyone is shopping in a softer market and assuming the discount is real.

If you are buying, selling or holding, check the street before you check the search result. Talk to us about a street-level assessment of the exact address you are considering, and make the decision on evidence the portal was never built to give you.
