Buyer’s Agent vs Real Estate Agent — The Difference That Costs Unrepresented Buyers Thousands
The confusion that costs buyers money
A significant share of Australian property buyers still don’t understand a foundational distinction: the real estate agent standing at an open home works for the seller, not for them. This isn’t a secret or a trick — it’s clearly disclosed and legally required — but it’s also routinely misunderstood by buyers who treat the selling agent’s friendly, helpful demeanour as evidence of neutral representation. It isn’t, and understanding why matters to your bottom line.
What a real estate agent (selling agent) is legally obligated to do
A real estate agent listing a property for sale is engaged by, and owes a fiduciary duty to, the vendor. Their legal and professional obligation is to secure the best possible price and terms for the seller — that’s the entire basis of how their commission is structured and how the law treats the relationship. Everything a selling agent does during a campaign, including how they manage buyer enquiries, is filtered through that obligation, even when the interaction feels collaborative and friendly from a buyer’s side of the conversation.
What a buyer’s agent is legally obligated to do instead
A buyer’s agent (or buyer’s advocate) is engaged directly by, and owes fiduciary duty to, the buyer. Their entire professional existence is built around representing purchaser interests — sourcing suitable properties, assessing genuine value independent of the vendor’s asking price, and negotiating or bidding specifically to minimise what the buyer pays while securing the property they want.
Why this distinction has real financial consequences
When an unrepresented buyer asks a selling agent “what’s the lowest the vendor will accept?”, the agent’s obligation is to answer in a way that serves the vendor’s interest — which is rarely the buyer’s interest. This isn’t dishonesty; it’s the system working exactly as designed. The problem is that many buyers don’t fully register this while they’re standing in a property they’ve fallen in love with, mid-conversation with someone who has been genuinely helpful and pleasant throughout the process.
A buyer’s agent exists specifically to remove this asymmetry — providing a professional on the buyer’s side of the table with the same obligation to buyer interests that the selling agent has to vendor interests.
Can the same person ever act as both?
No — this would represent a direct conflict of interest and is not how the roles are structured in Australian real estate. A professional cannot simultaneously hold a fiduciary duty to both the buyer and the seller in the same transaction; the two roles are, and must remain, entirely separate.
Where the confusion most commonly costs buyers
At open homes. Buyers frequently ask the selling agent questions that only make sense to ask a professional representing their own interests — questions about likely final price, vendor motivation, or negotiation strategy — without registering that the answers they receive are filtered through the agent’s obligation to the seller.
At auction. An unrepresented buyer bidding against experienced buyers, and sometimes against buyer’s agents representing other bidders, is navigating a competitive, emotionally charged process without independent counsel on when to stop.
In negotiation generally. A selling agent’s job during negotiation is to extract the best terms for their client — the vendor. An unrepresented buyer negotiating directly is, in effect, negotiating against a trained professional whose entire job is to get the best outcome against that buyer’s interests specifically.
When a buyer’s agent’s value is clearest
The gap this creates is most pronounced for buyers who are time-poor, unfamiliar with a specific market (interstate or overseas buyers, in particular), inexperienced with auction dynamics, or simply uncomfortable with high-stakes negotiation. Data cited by industry bodies including REBAA consistently shows a large majority of buyer’s agent clients believe the engagement delivered a materially better outcome than they’d have achieved unrepresented.
The “double agent” warning REBAA has raised directly
This isn’t a purely theoretical conflict-of-interest concern. REBAA has publicly warned about real estate arrangements where a single agency or individual attempts to represent both a buyer and seller’s interests in overlapping ways — sometimes described in industry commentary as “double agents” — creating exactly the fiduciary conflict the buyer’s agent role exists to prevent. The association’s guidance is explicit that a professional cannot hold genuine, undivided loyalty to both sides of the same negotiation simultaneously, regardless of how the arrangement is marketed to the buyer. If a buyer ever encounters an offer that blurs this line — a selling agent suggesting they can also “look after” the buyer’s side informally, for instance — REBAA’s own public commentary treats this as a red flag worth walking away from, not a convenient shortcut worth accepting.
How to tell within the first conversation
A practical test costs nothing and takes one question: ask directly, “who do you represent in this transaction, and who pays your fee?” A selling agent should answer unambiguously that they represent the vendor and are paid by the vendor. A buyer’s agent should answer unambiguously that they represent you and are paid by you (or, in some hybrid retainer models, partly by you upfront with the balance at settlement — but always disclosed as coming from the buyer’s side). Any answer that hedges, or implies dual loyalty, is worth treating with real caution before proceeding further.

Frequently Asked Questions
If I’m buying, should the selling agent’s advice be ignored entirely? Not ignored, but understood in context — a selling agent’s factual information about a property (condition, inclusions, settlement flexibility) is generally reliable, while any advice touching on price strategy or negotiation should be weighed knowing their obligation runs to the vendor.
Does a buyer’s agent cost more than just dealing directly with the selling agent? A buyer’s agent charges a fee (commonly 1.5–2.75% of purchase price or a fixed fee), whereas dealing directly with a selling agent carries no separate cost to the buyer — the comparison that matters is whether the buyer’s agent’s fee is offset by a better negotiated outcome, which REBAA-cited buyer surveys suggest is the case for a large majority of buyer’s agent clients.
Can a real estate agent legally represent both a buyer and seller in the same transaction? No — this constitutes a direct conflict of interest under Australian real estate regulation and is not a legitimate dual-representation arrangement.
Is “buyer’s advocate” a different qualification to “buyer’s agent”? No — the terms are used interchangeably across Australia, with “buyer’s advocate” more common terminology in Victoria and “buyer’s agent” more common in NSW and Queensland, referring to the same licensed role.
How do I check which side of a transaction a specific professional is representing? Ask directly and explicitly — a licensed professional is required to disclose who they represent, and if a selling agent’s answer to “are you representing me or the vendor” is anything other than an unambiguous clarification that they represent the vendor, that itself is worth further scrutiny.
