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.
For all eight states and territories in one place, see our state-by-state guide to real estate agent fees in Australia.
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% to 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% to 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% to 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 to $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 to 1% of property price rule of thumb translates to $3,250 to $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 to $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 to $2,200.

Other selling costs in brief
Beyond commission and marketing, South Australian sellers commonly incur:
- Conveyancing and legal fees: $500 to $2,200
- Building and pest inspection (pre-sale, optional): $450 to $900
- Home staging (optional): $2,000 to $8,000
- Mortgage discharge fee (if applicable): bank fee $150 to $600 plus government registration ~$100 to $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 sends one brief, at once, to the buyers agents who match your property, from our list of 85+, each of whom has buyer clients in their pipeline. Our list is researched; not every agent on it is a member yet. SA properties attract consistent interstate buyer interest, particularly from Victoria, NSW and expats; buyers agents are well positioned to reach that cohort.
AgentBridge's distribution fee is a published marginal scale, plus GST: 1.6% on the part of the sale price up to $600,000, 1.4% on the part from $600,000 to $1,500,000, 1.2% on the part from $1,500,000 to $3,000,000 and 1.0% on the part above $3,000,000. Each rate applies only to the part of the price inside its band. For example, on a $750,000 sale the distribution fee is $11,700 plus GST ($12,870 including GST). The residential minimum is $4,000 plus GST.
No part of the distribution fee goes to a buyers agent; the buyers agent who introduces the buyer is paid by their own buyer client.

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% to 3.0%. Adelaide metro averages sit around 1.61% in several sources, though other sources quote 2.0% to 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.
