That response is understandable. Commission is the most visible cost in a property sale. Because it is tied to a sale price that has not yet been determined, it becomes the easiest number to compare - and so it becomes the one vendors compete on, even when it is not the most important variable.
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 $3,750 gap is real. But focusing on it alone means optimising for an input cost while ignoring the output that determines whether that cost was worth paying at all.
The Maths Most Sellers Skip
Comparing commission rates against each other is the wrong exercise. Comparing expected net proceeds is the right one.
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.
What separates a good result from an average one on a comparable property is rarely the market. It is the campaign. How buyers are attracted, qualified, and then managed through negotiation is where the difference is made - and that difference shows up directly in the settlement figure.
The Real Value Behind the Percentage
A commission is not payment for a listing and a sign. Those are the minimum. The value in a real estate fee sits in everything that happens after the property goes live - and most of that work is invisible to the vendor.
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.
It is also strategic marketing. Professional photography, floor plans, portal listing quality, and in some cases property styling coordination. These costs are sometimes included in the commission and sometimes charged separately. Vendors should confirm this before signing an agreement, because a low commission rate that excludes marketing can end up costing more in total than a higher rate that includes it.
Most homeowners sell only a handful of properties across their lifetime. That limited experience makes it genuinely difficult to evaluate what good agent performance looks like - which is why the commission figure becomes the proxy. It is the one number that is easy to compare. But easy to compare is not the same as meaningful to compare.
A Better Set of Questions Than What Is Your Commission
The commission conversation becomes more productive when it shifts from rate to performance. These questions are worth asking before any agency agreement is signed.
- 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?
These questions shift the conversation from input cost to expected output. An agent who answers them with specifics is demonstrating the competence that justifies their fee. An agent who deflects toward market conditions or general reassurances is not.
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.
Local Market Perspective
For residential vendors across the Gawler District, the real estate agent fee question is best answered by looking at net proceeds rather than commission percentages in isolation.
Gawler East Real Estate
supports residential vendors across the Gawler District and surrounding northern Adelaide suburbs with evidence-based property appraisals and home sales services, at a commission of 1.5 percent inclusive of GST - an independent agency rate that keeps the cost of selling transparent while the outcome remains the measure that matters.
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.
Does commission include marketing costs?
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.
