Real Estate Commission SA: Average Rates & Agent Fees (2026)

Average real estate commission in SA

Real estate commission in South Australia typically ranges from 1.8% to 2.75% of the final sale price, with 2% the most common rate. Commission is a percentage of the price the property actually sells for, it is paid by the seller out of the sale proceeds at settlement, and it is negotiable.

SA sits towards the lower-to-middle end of the national picture. The typical 2% in Adelaide and across South Australia is in line with the bigger eastern-state capitals and below the higher rates more common in Western Australia, the Northern Territory and parts of regional Australia. Lower sale prices in some SA markets can nudge percentage rates up a little, because the agent’s costs are spread over a smaller number, while competitive metropolitan Adelaide suburbs tend to keep rates closer to the 2% mark.

Because commission is charged as a percentage, the dollar figure rises with the sale price even at the same rate. That is exactly why the rate is worth a conversation, and why it pays to see the number in dollars rather than as a percentage.

What that costs on your sale price

Here is what those rates work out to in dollars across a range of SA sale prices. The figures show the lower end (1.8%), the typical rate (2%) and the higher end (2.75%), so you can see the spread on your own likely price.

These figures exclude GST, which is usually added on top, and they exclude marketing and other selling costs. For an exact figure on your own sale price, use our commission calculator, which has a South Australia setting.

How commission is structured in SA

Most South Australian agents charge a flat percentage of the sale price. Some offer a tiered or performance-based structure instead, where the rate steps up on the amount achieved above an agreed target price, which rewards the agent for pushing past a benchmark and can align their incentive with yours. A flat percentage is the most common, but a performance clause is worth asking about, especially if you think there is upside in a strong campaign.

The norm in SA is “no sale, no fee”: commission is only payable if the property sells, usually at settlement out of the proceeds. You do not pay the commission up front.

What the commission normally covers:

• Appraisal and pricing strategy, the agent’s read on what the home should sell for and how to take it to market.
• Listing and management of the campaign through to settlement.
• Open homes and private inspections, hosting buyers and qualifying enquiry.
• Negotiation with buyers on your behalf to achieve the best price and terms.

What is usually charged separately, on top of commission:

• Marketing and advertising, including listings on the major property portals and any print or digital campaign.
• Professional photography, and often video or floor plans.
• Property styling or staging, where you choose to use it.

Is commission negotiable in SA?

Yes. Commission in South Australia is deregulated, so there is no government-set rate and every agent sets their own. The percentage on the first agency agreement you read is an opening number, not a fixed price, and most sellers can move it with a straightforward conversation.

How to negotiate the rate in SA:

• Compare two or three local agents. Getting competing appraisals gives you the leverage and the information to push on the rate.
• Negotiate on the rate and the marketing. A slightly lower percentage means little if the marketing budget is padded. Treat both as part of the same deal.
• Be wary of the cheapest. The lowest rate is not the best outcome if it comes with a thin campaign or an agent juggling too many listings. A good agent who achieves more on the sale earns their fee back many times over.
• Get it in writing. Confirm the rate, whether GST is included, and what marketing costs sit on top, all in the agency agreement.

For a sense of what is normal and who is licensed, the Real Estate Institute of South Australia (REISA)is the state’s industry body, and agents in SA are licensed and regulated through Consumer and Business Services SA. Checking that an agent is properly licensed is a basic first step before you hand over your largest asset.

Commission vs your other selling costs

Commission is the largest single cost of selling, but it is not the only one. Marketing and photography, conveyancing or legal work, styling and any presentation work all sit alongside it, and if the property is an investment rather than your home, capital gains tax can be larger again.

Get an appraisal and the right agent

The commission rate matters, but the agent you choose usually matters more. The right agent in SA will achieve a higher price than the cheapest one, often by enough to cover the difference in the rate several times over. So the order that saves the most is to value the home, choose the agent well, then negotiate the fee.
