Buyer's Agent vs Real Estate Agent — The Victoria Legal Definition (2026 Guide)

If you are searching "buyer's agent vs real estate agent Australia" in 2026, you are asking one of the most under-explained questions in Australian property. The two professions are commonly conflated, frequently misrepresented in marketing material, and governed in Victoria by the same statute — the Estate Agents Act 1980 (Vic) — under the same licensing regime administered by Consumer Affairs Victoria. Yet they sit on opposite sides of every transaction, owe fiduciary duties to opposing parties, and operate under conduct rules that make any blurring of the line a regulatory matter.

The distinction is simple in principle. A real estate agent (also called a selling agent or listing agent) acts for the vendor — the seller. They are paid by the vendor, owe their fiduciary duty to the vendor, and their job is to maximise the sale price. A buyer's agent acts for the purchaser. They are paid by the purchaser, owe their fiduciary duty to the purchaser, and their job is to minimise the purchase price and maximise the strategic fit of the property to the buyer's brief.

"Most consumer confusion happens because both wear the same shirt and carry the same business card," I tell clients. "They are both 'estate agents' under Victorian law. The difference is who they work for, and that distinction governs every conversation, every disclosure, and every dollar."

The legal foundation: Estate Agents Act 1980 (Vic)

The Estate Agents Act 1980 (Vic) is the principal statute governing both selling agents and buyer's agents in Victoria. The Act, administered by Consumer Affairs Victoria and the Estate Agents Council, defines an "estate agent" broadly enough to capture both functions:

An estate agent is a person who, on behalf of any other person and for reward, performs any act of negotiation, introduction, sale, purchase, exchange, leasing, or letting of any real estate.

The statute does not create separate licence classes for buyer-side and sell-side. A single Victorian Estate Agent's licence authorises both activities. This is unlike financial services, where Australian Financial Services Licence (AFSL) authorisations distinguish between advice provided to retail clients and advice provided to wholesale clients with corresponding conduct obligations.

The practical implication is that a Victorian Estate Agent's licence by itself does not tell a consumer whether the holder is acting for buyers or sellers — that is determined by the agency agreement signed in each individual transaction. Section 49A of the Estate Agents Act 1980 requires this agreement to be in writing and signed before any work commences, and it must clearly identify the principal (the party the agent is acting for).

The related regulations — the Estate Agents (Professional Conduct) Regulations 2018 — prescribe specific conduct standards including disclosure obligations, conflict-of-interest rules, and trust-account handling. These apply to all estate agents regardless of which side of the transaction they are on.

Fiduciary duty — the hardest legal distinction

A fiduciary duty is the highest legal duty one person can owe another in commercial dealings. It is not a contractual term — it is imposed by common law and equity on any agent acting on behalf of a principal. The duty includes:

• Loyalty — the agent must act in the best interests of the principal at all times.
• No conflict — the agent cannot have any undisclosed personal or commercial interest that conflicts with the principal's interests.
• No profit — the agent cannot make any unauthorised profit beyond the agreed fee.
• Confidentiality — the agent cannot disclose the principal's confidential information to the other party.
• Full disclosure — the agent must disclose all material information that affects the principal's interests.

For a real estate agent, the principal is the vendor. So when a real estate agent tells a prospective buyer at an open inspection "we have other offers coming in this weekend," they are doing their job for their principal — creating competitive pressure to maximise the sale price. They are not lying to the buyer in a way that breaches their duty, because the buyer is not their principal.

For a buyer's agent, the principal is the buyer. Every piece of advice, every negotiation tactic, every recommendation must be directed to advancing the buyer's interests. A buyer's agent who steers their client to a developer offering a 4 to 6 per cent kickback (without disclosure) is breaching fiduciary duty even though the same conduct by a real estate agent on the other side of the table would be entirely permissible.

This is why the question "who is the principal?" is the most legally important question in any real estate engagement. The Real Estate Buyers Agents Association of Australia (REBAA) code of conduct goes further and requires members to refuse vendor-side payments altogether — a higher voluntary standard above the legal baseline.

The rule against dual agency

Dual agency — the same agent acting for both buyer and seller in the same transaction — is generally prohibited under Australian common law and Victorian regulation because the conflict of interest is irreconcilable. An agent cannot simultaneously discharge a duty of loyalty to maximise the sale price (for the vendor) and a duty of loyalty to minimise the purchase price (for the buyer).

In limited circumstances, dual agency may be permitted only with the fully informed written consent of both parties — a high bar that requires complete disclosure of all conflicts and acceptance by both parties. In practice, very few transactions in Victoria meet this standard, and dual agency is a regulatory red flag.

What consumers should watch for in 2026:

• A "buyer's agent" who is also paid a referral fee by the developer of a project they recommend — this is structurally close to dual agency and is at minimum a disclosable conflict.
• A real estate agent who offers to also act as the buyer's representative for an off-market deal — this is dual agency in everything but name.
• A property advisory firm whose income is split between buyer fees and developer commissions — REBAA members cannot operate this model; non-members can but should disclose.

Under section 47 of the Estate Agents Act 1980, an estate agent who acts in conflict of interest without proper disclosure can face cancellation of their licence, fines, and civil liability for any loss the principal suffers. Consumer Affairs Victoria publishes annual disciplinary actions and a small but consistent number relate to undisclosed dual representation.

Verifying a Victorian Estate Agent licence — 60-second guide

Whether the agent calls themselves a buyer's agent, a buyer's advocate, a property advisor, or a real estate agent, they must hold a current Victorian Estate Agent's licence to operate legally. Verification is free and takes 60 seconds:

1. Open the Consumer Affairs Victoria website at consumer.vic.gov.au.
2. Navigate to "Licensing and registration" → "Estate agents" → "Public register".
3. Search by licence number if you have it, or by individual or business name.
4. Confirm the licence is current — the register shows current, suspended, and cancelled licences.
5. Check disciplinary history — the register includes any disciplinary action taken by the Estate Agents Council.

If the agent does not appear on the register, they are operating illegally. Any agreement you sign with them is unenforceable, and any fee you pay may not be recoverable through normal channels. Reporting unlicensed activity to Consumer Affairs Victoria is the appropriate next step.

A second verification specifically for buyer's agents is REBAA membership, searchable at rebaa.com.au/find-an-agent. REBAA membership is voluntary and is not a substitute for the Victorian licence, but it is a meaningful additional buyer-side accreditation.

Common consumer confusion — five real examples

These are five conversations I have had with prospective clients in 2024-2025 that all stemmed from the same underlying confusion:

Example 1. A prospective buyer engaged with a "buyer's agent" recommended by a developer at an investor seminar. After paying $7,000, the buyer discovered the agent was being paid an additional 5 per cent commission by the developer for any sale closed. The agent's effective income was being driven by the vendor side of the transaction, not the buyer side.

Example 2. A prospective buyer at an open inspection asked the selling agent for honest advice on whether the property was a good investment. The selling agent, with full sincerity, said yes. The buyer interpreted this as independent professional advice. It was not — it was a vendor-side agent doing their job for their principal.

Example 3. A prospective buyer engaged a real estate agent to "help them buy" a specific listed property. The agent agreed informally without a written buyer's agency agreement. When the contract negotiation began, the seller's lawyer pointed out the agent was acting on the seller's behalf under the listing agreement. The buyer had no agent at all.

Example 4. A prospective buyer received a marketing email from a "property advisor" offering a free strategy session. After a 90-minute meeting, they were presented with three off-the-plan apartments — all from the same developer paying the advisor 4 per cent commission. The advisor held a Victorian Estate Agent's licence and was therefore lawfully entitled to operate, but had not disclosed the developer relationship.

Example 5. A prospective buyer assumed their conveyancer was acting as their buyer's agent for property selection. Conveyancers handle the legal transfer of title, not the strategic property decision. The buyer purchased a property that turned out to be subject to a Heritage Overlay restricting any future renovation — a fact a competent buyer's agent would have surfaced during due diligence.

In each case, the confusion was not about competence — it was about whose principal the relevant party was acting for. The Estate Agents Act 1980 (Vic) and the fiduciary duty framework work as intended, but only when consumers understand who is on which side of the table.

If you are unclear whether a prospective agent is acting for you or for someone else, ask three questions in writing. First: "Who is your principal in this engagement?" Second: "Are you receiving any payment from any party other than me?" Third: "Will you sign a written buyer's agency agreement under section 49A of the Estate Agents Act 1980 before any work begins?" The answers will tell you everything.
