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.
Two vendors. Comparable properties. One negotiates a 1.5 percent commission and sells for $740,000 - netting $728,900. The other pays two percent and sells for $765,000 - netting $749,700. The agent with the higher rate delivered $20,800 more into the the vendor account. The commission conversation the first vendor was so focused on cost them the equivalent of several years of savings.
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.
What Commission Actually Covers
When a vendor pays a real estate commission, they are not paying for the agent to place a sign on the front lawn and list the property on a portal. That is the baseline expectation - not the value proposition.
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.
What to Ask Instead of Negotiating the Rate
Rather than opening with what is your commission, the questions below are likely to tell a vendor far more about what they are actually buying.
- 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?
An agent who can answer these with specifics is showing their work. An agent who responds with vague market commentary is telling you something important about how they operate.
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.

Real Estate Commission - The Questions Worth Asking
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?
At 1.5 percent, a $750,000 sale in South Australia produces an agent fee of $11,250 inclusive of GST. At two percent, that becomes $15,000. The difference between rates compounds at higher price points. At $900,000, the gap between 1.5 and 2.5 percent is $9,000 - which is why total cost of selling and expected sale outcome both need to be part of the comparison.
