The first number a buyer's agent puts on the table is almost never the last number you will pay to complete a purchase. Stamp duty, inspections, a conveyancer and the agent's own tax invoice sit beside it. The fee itself is also less fixed than the brochure implies. There is no statutory scale for this work in Australia. Public consumer sites say the charge is negotiable and is not set by law. Anyone who tells you "the government rate is X" is inventing a schedule that does not exist.

That does not mean the market is a mystery. It means you should read a quote the way you would read a building report: as a claim about one job, in one city, at one service level, written by a person who wants the work.

This is the hub piece for our fees and contracts section. It explains the industry-reported bands, the GST rule, the money that arrives before the search, and the three questions that decide whether a handsome percentage is actually the cheaper path. If you want the job described before the invoice, start with what a buyer's agent does.

There is no official fee schedule

Real estate selling commissions have always attracted folklore — "the standard is 2 per cent" — and buyer's agency has inherited the same habit. Folklore is not a regulator. NSW Fair Trading, Consumer Affairs Victoria and WA Consumer Protection spend their pages on authorities, rebates and conflicts, not on a price list you can pin to the fridge.

The practical consequence is simple. Two licensed firms in the same suburb can charge different amounts for different scopes and both can be telling the truth. A negotiation-only job on a house you already found is not the same product as a three-month search across four postcodes. Comparing the headline percentages without comparing the work is how people feel cheated by a fee that was, on its own terms, disclosed.

Treat every figure in this article as a way to interrogate a quote, not as a substitute for one.

What the industry actually reports

The Real Estate Buyers Agents Association of Australia, REBAA, describes a full-service industry average somewhere around 2 to 3 per cent of the purchase price plus GST and an engagement fee. The same commentary allows for a flat fee plus an engagement fee instead of a percentage. That is the band we are prepared to repeat, because it is attributed industry commentary rather than a number we invented in this newsroom.

It is still only a band. A 2 per cent fee on a $800,000 regional purchase is a different invoice from 2 per cent on a $2.4 million house in the inner east of Melbourne. A "modest" fixed fee in Sydney can exceed a mid-range percentage in a cheaper city. The percentage is a method. The dollar figure is the cost.

Full service, in the sense REBAA is talking about, is the long product: a written brief, the search, shortlisting, inspections, due diligence, negotiation or auction, and a file that stays open through settlement. Plenty of firms also sell slices of that work. Auction-only and negotiation-only packages cost less because the search hours are gone. Search-and-shortlist packages sit in the middle. The authority should name the slice you are buying. A vague promise to "assist you to purchase a property" is how a success fee attaches to a house you found on your phone.

What you are buying when you buy a percentage

A commission calculated on the purchase price rises as the price rises. That can be easy to explain at a kitchen table and awkward to sit with in a bidding war. The agent does not automatically become richer by talking you into a worse deal — a failed campaign earns them nothing on the success fee — but the incentive is not symmetrical. Saving you $40,000 trims their percentage. Getting you over the line at the top of the brief does not.

That is not an argument against percentages. It is an argument for a written limit, a brief that includes the fee inside the budget, and a person you trust to tell you the house is not worth the last bid. The fixed fee versus commission piece works through the incentives in more detail. The short version for this page is: pick the model after you pick the scope, not before.

A percentage also needs a base. Is it the purchase price only? Does it include GST on the fee, or is GST added later? Is there a minimum dollar fee so that a cheaper house still produces a viable invoice? Minimums are common enough that you should ask, even when the conversation began with "we charge 2 per cent."

Engagement fees sit on top of the headline number

Many firms take an engagement fee or retainer when you sign. It is often credited against the success fee if you complete a purchase through them. It is often not refunded if you never buy, or if you end the authority early. Those two sentences can both be true in the same shop, which is why the credit has to be written down rather than nodded through.

The engagement fee is not a secret extra invented to pad this article. It is part of the REBAA description of the average full-service arrangement, and it is part of most authorities we are shown by readers. What varies is the size, the refund rule, and whether the firm will start serious work before the money clears. We wrote a separate piece on engagement fees and retainers because the upfront invoice is where a lot of regret starts.

Do not add the engagement fee to the success fee in your head and then forget that one may cancel the other. Do not subtract it either, until the authority says the credit is automatic.

GST is not an optional extra

Australian Consumer Law requires a single price that includes GST. If you are a consumer being quoted a price, the number you are given should already contain the tax. A conversation that lives in "plus GST" language is unfinished. Ask for the GST-inclusive figure in the authority, on the website, and in the email that follows the meeting.

This is not pedantry. On a mid-six-figure success fee the tax is a real line in the settlement budget. Buyers who planned to the last dollar of stamp duty and then met GST on the agent's invoice are not confused. They were given an incomplete price.

The same rule applies to fixed fees. "Fifteen thousand plus GST" is not the single price. The single price is the number you can pay without reaching for a calculator.

The three questions that decide the real cost

A fee that looks tidy on page one of a proposal can become a different fee in three ordinary situations. Ask all three before you sign, and ask them in writing.

What happens if you do not buy? Some campaigns end because the brief was wrong, the market moved, or you decided to stay put. If the engagement fee is gone and a time-based charge then starts, you need to know that while you still have a choice.

What happens if you buy a property they never showed you? Exclusive authorities sometimes treat any purchase in the listed suburbs, during the listed term, as a success. That can be fair if they have been working the brief. It can also be a trap if your sister texts you a listing and you buy it on Saturday. The trigger for the success fee belongs in a sentence you can read aloud.

What happens if you terminate? Authorities have end dates. They also have early-exit clauses, leftover disbursements, and the occasional attempt to keep a success fee alive after the relationship has soured. NSW Fair Trading, Consumer Affairs Victoria and WA Consumer Protection all put weight on written authorities for a reason. The paper is the job. If you want a checklist for walking away from a bad one, use the red flags guide and the broader checks hub.

Those three questions sort a professional shop from a brochure faster than any discussion of comparable sales.

Rebates and the money you never see

The invoice you pay is not the only way an agent can be paid. Referral relationships with brokers, inspectors, conveyancers and developers can produce rebates or commissions that never appear on your settlement statement. NSW Fair Trading, Consumer Affairs Victoria and WA Consumer Protection warn buyers about rebates and tell you to get the arrangement in writing. Ask the question in the first meeting. Ask it again when the authority is in front of you. If the answer is "we would never," ask them to write that down too.

A rebate is not automatically corrupt. An undisclosed rebate is a conflict you did not agree to. The buyer's agency authority is the document that should name every way the firm can earn money from your campaign.

"Free" buyer's agents inside a selling office are a different problem. If nobody is sending you a tax invoice, someone else is paying. That someone is rarely you, which means the duty of care is pointing at a different chair.

How to compare two quotes without a spreadsheet

Write the same brief twice. Same suburbs, same budget including costs, same service level, same timeline. Then ask each firm for a single GST-inclusive price, the engagement fee, the credit rule, the success trigger, the termination rule, and a sentence on rebates. If one firm will only talk in percentages and the other will only talk in dollars, convert both to dollars on a house at the middle of your brief and on a house at the top. The model that looks cheaper in the middle sometimes loses at the top.

Check the licence before you fall in love with the cheaper number. A discount from an unlicensed operator is not a saving. Our licence check walk-through sits in the checks hub for that reason. Membership of a body such as REBAA is a signal. It is not a substitute for the public register in the state where the property sits.

Then look at the work. A lower fee that excludes inspections, auction day, or any property outside two named streets is not a lower fee. It is a different job. How to choose a buyer's agent is the piece for the interview. This page is the piece for the arithmetic that follows it.

When a cheaper fee is the expensive choice

The fee earns its keep when it changes an outcome you could not have produced alone: a walk-away from a pretty house with a bad roof, a bid that stops at a number you can explain, a search that finds the floorplan you wanted in a suburb you had written off. It is a poor purchase when you have already chosen the only house you will buy, the campaign is quiet, and a sharp conveyancer is already on the file. In that case a negotiation-only engagement — or no agent — may be the adult decision.

Interstate buyers, time-poor buyers and people who freeze on auction day are the usual cases where the dollar fee is easier to defend. First-home buyers sometimes hire a full-service firm because the process is new, then discover they needed a teacher more than a searcher. Teaching is not always in the authority. Ask.

Investors should put the fee into the yield maths before they sign, not after the first inspection. A percentage that looked harmless on a purchase-price slide can wipe the first year of rent. That is not an argument against hiring help. It is an argument for putting the help on the same page as stamp duty.

A worked example, not a quote

Imagine a couple with a ceiling of $1.4 million including costs, looking in a pocket of Brisbane where comparable houses have been trading in a band that makes a $1.25 million purchase plausible. A 2.5 per cent success fee on $1.25 million is $31,250 before you even discuss GST or an engagement fee. If the firm quotes in the REBAA-style way — percentage plus GST plus an engagement fee that is later credited — the GST-inclusive success fee is the number to put in the budget, and the engagement fee is a cash-flow item rather than an extra layer of profit, provided the credit is real.

Move the same couple to a fixed fee of $22,000 including GST, with a $4,000 engagement fee credited against it. On that particular house the fixed fee is cheaper. Move them to a $1.7 million house that only appears in week ten, and the comparison flips or holds depending on whether the fixed fee had a cap, a reset, or a "premium property" clause you missed on page four.

None of those figures is a market rate. They are arithmetic on made-up quotes, which is the only honest way to do a worked example when there is no official schedule. Do the same arithmetic on the real letters you are holding.

The short version

Buyer's agent fees in Australia are negotiated, not gazetted. REBAA's reported full-service average — around 2 to 3 per cent of the purchase price plus GST and an engagement fee, or a flat fee plus an engagement fee — is a way to recognise a quote, not a way to write one. Demand a single GST-inclusive price. Get the credit, the success trigger and the termination rule in the authority. Ask about rebates. Then decide whether you are buying a full search or a day's negotiation. The cheapest signature is the one that matches the job you actually need.
