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.
The Number That Actually Determines Your Result
The commission rate comparison is a distraction. The calculation that actually matters is what lands in your account after the sale completes.
Consider two scenarios. In the first, a vendor negotiates a 1.5 percent commission with an agent who achieves a sale price of $740,000. Net after commission: $728,900. In the second, a vendor pays a two percent commission to an agent who achieves $765,000. Net after commission: $749,700. The vendor who paid the higher commission rate walks away with $20,800 more.
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 gap between an average result and an excellent one does not usually come down to luck or timing. It comes down to how well the agent manages the campaign - days on market, buyer qualification, how competing interest is handled and converted. These skills are not visible on a commission comparison sheet.
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.
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?
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.

Agent Fee Questions - Answered
Is there a set commission rate for real estate agents 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.
Is it worth negotiating real estate agent fees?
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 am I actually paying for with a real estate 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 is real estate commission calculated?
Commission on a $750,000 South Australian property ranges from $11,250 at 1.5 percent to $18,750 at 2.5 percent inclusive of GST. That $7,500 range is meaningful. But it becomes less meaningful when set against the potential $15,000 to $25,000 difference in sale price that can exist between a strong campaign and an average one.
