South Australia · the short answer

About $23,650 to sell a $720,000 house in SA

South Australia sits in an awkward spot on selling costs. The median house price is roughly half Sydney’s, but the average commission rate of 2.5% is higher than both NSW and Victoria. SA sellers pay a bigger percentage of a smaller number, and the dollar result still reaches $18,000 at the median.

SA COST BREAKDOWN

Every cost of selling a house in South Australia

SA also has a document with teeth: the Form 1 vendor’s statement, which must be served on the buyer before the cooling-off clock starts. Here is the full cost list for an SA sale at 2026 rates.

Agent commission (2.5% SA average)

$18,000

The big one, and the only optional line on this list. At the SA average of 2.5% on a $720,000 sale, this is about $18,000. Commission is unregulated in South Australia, so the rate is set by the agency and is negotiable.

Marketing and advertising (VPA)

$2,000 – $5,500

Photography, floorplan, portal listings, signboard and brochures. Payable whether or not the house sells, and usually invoiced before the campaign starts.

Your conveyancer

$900 – $1,700

Handles the contract, Form 1 (Vendor Statement), searches and settlement on your behalf.

Form 1 (Vendor Statement) and searches

$200 – $450

South Australia requires a Form 1 vendor disclosure statement, covering title, encumbrances, council and statutory details, to be served on the buyer before settlement.

Mortgage discharge and registry

$200 – $350

Your lender’s fee to release its mortgage over the title, plus the land registry fee. If you are breaking a fixed rate, ask for the break cost in writing separately.

Auctioneer (only if you auction)

$400 – $800

The auctioneer’s fee on the day. Buyers in South Australia get a 2-clear-business-day cooling-off period on private-treaty sales. There is no cooling-off period at auction (or if the buyer bought at auction within 3 days).

SA SPECIFIC

The Form 1 has to be served, not just prepared

South Australia requires a Form 1 vendor’s statement to be served on the buyer, and the cooling-off clock does not start until it is. Preparing it means paying for title, council and water searches and any strata or community records: $200 to $450, on top of your conveyancer’s fee. Serving it late is one of the most common and most expensive procedural mistakes in an SA sale.

Adelaide’s affordability cuts both ways

SA’s ~$720,000 median is well below Sydney or Melbourne, which keeps the dollar commission lower. But the state average rate of 2.5% is higher than NSW or VIC, so SA sellers pay a bigger percentage of a smaller number: about $18,000 at the median.

Form 1 service drives the cooling-off clock

The two-clear-business-day cooling-off period in SA runs from when the Form 1 is served, not from when the contract is signed. Get the sequencing wrong and you hand the buyer an extended right to walk, which can cost you the sale rather than just a fee.

Regional SA rates push past 2.75%

Outside Adelaide, agent supply thins and rates climb toward 2.75% to 3.0%. On a $450,000 regional median that is about $12,400 to $13,500, which on a modest sale price is a large share of the equity you were counting on.

Do SA sellers pay stamp duty? No.

Stamp duty on a property transfer is a buyer cost in South Australia, not a seller cost. The only tax that can land on a SA seller is capital gains tax, and that applies solely to investment properties, never to your main residence. Licensing and agent conduct in SA is governed by the Land and Business (Sale and Conveyancing) Act 1994 (SA).

SA WORKED EXAMPLE

A $720,000 SA sale, two ways

WITH A TRADITIONAL AGENT

$23,650

Commission of $18,000 at 2.5%, plus marketing, conveyancer fees, Form 1 (Vendor Statement) searches and mortgage discharge. Commission alone is about 76% of it.

WITH UNRESERVED

$2,800

A flat $900 replaces the commission and the marketing spend. You still pay your conveyancer, the Form 1 (Vendor Statement) searches and mortgage discharge, because those are not agent fees.

DIFFERENCE

$20,850

Same house, same portals, same buyers. This is the part of your equity that stays with you rather than funding a percentage.

Based on the SA median house of $720,000 at the state average commission of 2.5%, with mid-range marketing, conveyancer and search costs. Your actual figures depend on your sale price and the rate you would otherwise have negotiated.

FAQ · COST OF SELLING IN SA

Cost of selling a house in South Australia: common questions

How much does it cost to sell a house in SA?

On South Australia’s ~$720,000 median house, expect about $18,000 in commission at the state average of 2.5%, $2,000 to $5,500 in vendor-paid marketing, $900 to $1,700 for a conveyancer, $200 to $450 for Form 1 searches and $200 to $350 for mortgage discharge. Total: roughly $21,300 to $26,000, with commission about 76% of it.

What does a Form 1 cost in South Australia?

The searches behind a Form 1 vendor’s statement typically cost $200 to $450 (title, council and water, plus strata or community records where they apply). Your conveyancer’s fee to prepare and serve it usually sits inside their $900 to $1,700 seller fee. The Form 1 must be served on the buyer, and the cooling-off period does not start until it is.

What are agent fees for selling a house in SA?

South Australian agents average about 2.5% of the sale price, and regional SA runs closer to 2.75% or 3.0%. Commission is unregulated and negotiable. Vendor-paid marketing adds a further $2,000 to $5,500.

Do I pay stamp duty when selling a house in SA?

No. Stamp duty on a property transfer is paid by the buyer in South Australia. Sellers pay commission, marketing, conveyancing, the Form 1 searches and mortgage discharge. CGT applies only to investment properties.

How can I reduce the cost of selling my house in SA?

Commission is around three-quarters of what an SA sale costs, so it is the only line worth attacking. Unreserved lists your SA home on realestate.com.au and Domain, prepares and serves the Form 1 and runs the campaign for a flat $900, which on the SA median keeps roughly $17,100 that would otherwise be commission.

76% of your selling costs are optional.

Same portals. Same buyers. None of the 2.5% commission. List your South Australia home with Unreserved for a flat $900.
