That instinct is understandable. Commission is the most visible cost of selling a house. Because it is expressed as a percentage of an unknown sale price, it often becomes the number vendors focus on first - and the number they use to compare agents who may have very little else in common.
Real estate agent fees in Australia are not regulated at a national level. Individual states set the framework and within that framework agents set their own rates. In South Australia, commission is typically quoted as a percentage of the final sale price, inclusive of GST. Many independent agencies quote between one and 1.5 percent inclusive of GST. Many franchise agencies sit between two and three percent. The difference reflects overhead structure, brand costs, and service inclusions - not a straightforward measure of what the agent will actually deliver.
What that percentage translates to in dollar terms is where most vendors begin doing the maths. On a $750,000 sale, a two percent commission is $15,000. A 1.5 percent commission is $11,250. The difference is $3,750 and it feels significant. It is significant. But it is not the right calculation to be running.
Why Commission Is an Input Not an Outcome
The right calculation is not commission versus commission. It is net proceeds versus net proceeds.
Picture two vendors selling comparable properties in the same suburb. The first negotiates hard and secures a 1.5 percent commission, then achieves $740,000 at sale. Net proceeds: $728,900. The second pays two percent commission and achieves $765,000. Net proceeds: $749,700. The vendor who pushed less on the commission rate ends up $20,800 ahead.
This is not an argument against negotiating fees. It is the arithmetic that most vendors never complete because they are focused on the input cost rather than the output result.
The difference between an average sale and an excellent one is rarely explained by luck or market conditions alone. Days on market, negotiation approach, buyer qualification, how competing offers are managed - these are skills that vary significantly between agents, and they show up in the final number.
What Vendors Are Paying For When They Pay Commission
The sign and the portal listing are the starting point, not the service. What the commission is actually funding is harder to see and far more consequential.
It is the the agent existing buyer database - the pool of people who have already expressed genuine interest in properties of that type, price range, and location. It is the judgment to know when a buyer is ready to move and when another conversation will bring them further. It is the negotiation skill that, when two buyers are genuinely competing, extracts an extra $10,000 or $15,000 that an underprepared agent would have left on the table.
Strategic marketing is part of it too. Professional photography, floor plans, and portal presentation quality all influence how many buyers engage with a listing. These costs are sometimes bundled into the commission and sometimes invoiced separately. The total cost - commission plus marketing - is the figure that should be compared across agents, not the rate alone.
The average homeowner sells fewer than five properties in their lifetime. With that limited exposure, evaluating agent performance is genuinely hard. So the commission rate becomes the stand-in - it is concrete, comparable, and immediately actionable. The problem is that it measures cost rather than capability.
The Questions That Reveal What a Commission Rate Cannot
A more useful set of questions than what is your commission would include the following.
- What is your average sale price relative to your initial appraisal on comparable properties in this area?
- What is your average days on market for this suburb and price range over the past 12 months?
- How many buyers do you currently have registered who are actively looking in this area?
- How do you manage competing offers and what is your process for driving a stronger result when multiple buyers are interested?
- What is included in your commission and what is charged separately?
The answers separate agents who understand their own performance from agents who rely on the vendor not asking. Either way, the information is worth having before any agreement is signed.
The commission rate is a starting point for a conversation - not a conclusion. What a vendor is really trying to establish is whether the agent in front of them will generate a sale price that justifies every dollar of that commission and then some.
The commission is an input. Net proceeds are the outcome. When comparing agents, the question is not who charges the lowest percentage - it is who leaves you with the most money at settlement.

Frequently Asked Questions
How much commission do real estate agents charge in SA?
There is no fixed standard. Commissions in South Australia are set by individual agencies within a framework that allows negotiation. Many independent agencies operate between one and 1.5 percent inclusive of GST. Many franchise networks sit between two and three percent. The range reflects differences in overhead structure, brand model, and service inclusions rather than a direct measure of service quality.
Can you negotiate real estate agent fees in Australia?
Negotiating commission is reasonable, but the negotiation should not determine the decision. While some agents are happy to negotiate their rate, the stronger question is whether the agent can demonstrate a process and track record capable of delivering a better net outcome. A lower commission on a weaker sale result is not a saving.
What should be included in a real estate agent commission?
This varies by agency. Some agents include professional photography, floor plans, and portal listing fees within their commission. Others charge these separately as marketing costs. Before signing an agency agreement, vendors should confirm exactly what is included and request a written breakdown of any additional costs. The total cost of selling - commission plus marketing - is the figure that should be compared across agents, not the commission rate in isolation.
How much do real estate agents charge to sell a house?
On a typical suburban property in South Australia, a commission of 1.5 percent on a $750,000 sale produces a fee of $11,250 inclusive of GST. At two percent, the same property produces a fee of $15,000. At 2.5 percent, $18,750. The dollar difference grows significantly at higher price points, which is why understanding what the commission includes - and what the agent is capable of delivering - matters more as property values increase.
