Real Estate Agent Fees and Commission in SA (2026 Guide)
South Australia has an interesting commission landscape: Adelaide sits among the lower-commission capital cities in Australia, while regional South Australia can see rates well above the national average. Understanding that gap — and where your property sits within it — is one of the more useful pieces of due diligence a SA vendor can do before appointing an agent.
This guide covers how commission works in South Australia, what the current published data shows, and what the distribution model looks like as an alternative.

How commission works in SA
Listing agents in South Australia are paid a commission: a percentage of the sale price, drawn from settlement proceeds. Commission is only payable if the property sells — no sale, no fee.
Under the Land Agents Act 1994 (SA), agents must disclose their fees and charges in a Form 1 agency agreement before being appointed. The commission rate and any marketing charges must appear in writing. There is no government-set maximum or minimum rate; the amount is negotiated between vendor and agent.
Commission in South Australia is:
- Deregulated — no government-set cap or floor
- Negotiable — quoted rates are starting points
- Percentage of sale price — calculated on the final contracted price
- Payable at settlement — not upfront; only on a successful outcome
SA has no equivalent of Victoria's tiered commission frameworks as a widespread practice, though agents may propose them. The percentage model — a flat rate on the sale price — is the most common structure.
Average commission rates in SA
Based on published industry data as at June 2026, the following figures give a guide to the typical range for agent commission in South Australia. Sources disagree somewhat on exact averages, so the ranges are more useful than a single headline figure. Adelaide's figures in particular show notable variation across sources.
| Measure | Rate |
|---|---|
| State average | ~1.99% |
| Typical range | 1.6% – 3.0% |
| Adelaide metro average | ~1.61% |
Adelaide metro rates are among the lowest of any Australian capital in published sources. Outside metro Adelaide, rates generally climb: regional SA sees figures in the 2.75%–3.0% range and above in smaller centres. Published examples include Berri at around 3.24% and areas like the Adelaide Hills sitting around 2.0%. Note that SA sources show more internal inconsistency than most other states — some published ranges for Adelaide metro sit at 2.0%–2.75%, which contradicts the 1.61% average from other sources; both are recorded here because different data collection periods and methodologies appear to explain the gap.
All figures are estimates from published industry sources as at June 2026 and reflect market observations, not regulated rates.
Worked example — $650,000 sale price
The following table shows how commission translates to dollar cost at an example sale price of $650,000 (used as a broadly representative mid-range figure for South Australia — your property may differ significantly).
| Rate | Commission cost |
|---|---|
| 1.6% (low end) | $10,400 |
| 1.61% (Adelaide metro average estimate) | $10,465 |
| 1.99% (state average estimate) | $12,935 |
| 3.0% (high end) | $19,500 |
The spread from the Adelaide metro estimate to the high end — $19,500 versus $10,465 — illustrates how significantly location within South Australia affects the likely commission cost. For a regional SA vendor, the high-end figure is a realistic possibility; for an Adelaide metro vendor, the low end is closer to the expectation.

What commission does and does not cover
The commission a listing agent charges covers their professional service: appraising the property, managing the marketing campaign, running open inspections, presenting and negotiating offers, and coordinating through to settlement.
What commission generally does not cover:
- Marketing and advertising — typically a separate, upfront cost. Marketing spend in South Australia typically runs $400–$5,000 depending on the property, location and campaign depth. A standard Adelaide metro campaign sits in the middle of that range; a more comprehensive campaign for a premium property can exceed it. The 0.5–1% of property price rule of thumb translates to $3,250–$6,500 on a $650,000 property.
- Auctioneer's fee — auctions are less prevalent in SA than in VIC or NSW, but if your property goes to auction via a separately licensed auctioneer, the fee is typically $200–$1,000. Many SA agents hold an auctioneer's licence themselves; confirm whether a separate fee applies.
- Conveyancing — the vendor's solicitor or conveyancer prepares the Form 1 vendor statement, drafts the contract, and manages settlement. Seller-side conveyancing in SA typically costs $500–$2,200.

Other selling costs in brief
Beyond commission and marketing, South Australian sellers commonly incur:
- Conveyancing and legal fees: $500–$2,200
- Building and pest inspection (pre-sale, optional): $450–$900
- Home staging (optional): $2,000–$8,000
- Mortgage discharge fee (if applicable): bank fee $150–$600 plus government registration ~$100–$200
Figures are based on published industry data as at June 2026.
Negotiating the rate
Commission in SA is negotiable, and Adelaide's lower average rates suggest a competitive metro market where agents are already pricing to win business. That said, negotiation is still worthwhile.
Metro Adelaide. With rates already relatively low by national standards, the main negotiating levers in Adelaide are the marketing budget and the campaign structure. An agent who will move modestly on commission but offers a strong marketing plan and proven suburb experience may represent better overall value than one who offers a lower rate but a minimal campaign.
Regional SA. In regional South Australia, commission rates are higher and the agent pool is smaller. There may be less room to negotiate rate, but you can still compare agents on their track record, their buyer network and their approach to reaching interstate buyers — which is increasingly relevant for regional SA properties attracting retirees and lifestyle buyers from interstate.
Total cost comparison. Before comparing agents on commission rate alone, ask for their proposed marketing budget and confirm what is included. Commission rate and marketing spend together are the full agency cost to the vendor.
In writing. The Form 1 agency agreement must disclose all fees before you sign. Read it carefully.
The AgentBridge alternative
Traditional listing agents in SA, as in every state, market your property to whoever discovers it via portals and opens. For many SA properties — particularly in Adelaide — that audience is well served by portal listings. For properties at higher price points or in regional SA, it may not be.
AgentBridge distributes your property simultaneously to a national network of 80+ buyers agents, each of whom has pre-qualified buyer clients in their pipeline. SA properties attract consistent interstate buyer interest, particularly from Victoria, NSW and expats — buyers agents are well positioned to reach that cohort.
On a $650,000 sale in South Australia, a traditional listing agent at the state average commission estimate of 1.99% costs approximately $12,935. AgentBridge's distribution fee for the same property — which falls in the $600,000–$1,500,000 band — is 1.75%, or $11,375. That is a saving of approximately $1,560 against the average commission estimate. In regional SA, where commission is closer to 2.75%–3.0%, the saving is more significant: at 2.75% on a $650,000 sale the traditional commission is $17,875, compared to our distribution fee of $11,375.
The distribution fee includes the referral share paid to the buyers agent — no additional cost to the seller. This is the difference between an agent's commission and our distribution fee.

Frequently asked questions
Is agent commission regulated in SA?
No. Commission rates in South Australia are fully deregulated. There is no government-set minimum or maximum. The agent must disclose their fee in the Form 1 agency agreement before commencing, and the rate is negotiated between vendor and agent.
What is the average real estate agent commission in SA?
Based on published industry data as at June 2026, the state average is approximately 1.99%, with a typical range of 1.6%–3.0%. Adelaide metro averages sit around 1.61% in several sources — though other sources quote 2.0%–2.75% for Adelaide, suggesting data collection timing and methodology differences. Regional SA runs higher, with some centres near or above 3%.
Why is Adelaide commission lower than regional SA?
Adelaide is a competitive metro market. Higher transaction volumes and a larger agent pool tend to compress commission rates. Regional SA agents cover larger territories with fewer transactions per area and face less competition — both factors that support higher rates.
Does commission include marketing costs in SA?
Generally no. Marketing — portal listings, photography, signboard, floorplans, copywriting — is typically billed separately and upfront. Confirm all charges before signing the agency agreement.
