How much does it really cost to sell a house in Australia?

When people first think about selling, the usual mental shortcut is "the agent takes 2%". The real number is almost always higher once every line item lands, and the range between suburbs and states is wider than most sellers expect.

This guide walks through what actually comes out of your sale proceeds in Australia, what's negotiable, and where a flat-fee alternative changes the maths.

The big one: agent commission

Commission is the single biggest cost of selling for most sellers. Rates vary by state and suburb, but broadly:

• Metro Sydney / Melbourne: typically 1.8% – 2.5% of the sale price
• Metro Brisbane / Perth / Adelaide: typically 2.0% – 3.0%
• Regional areas: often 2.75% – 3.5%

On a $1.2m sale at 2.2%, that's $26,400. At 2.75%, it's $33,000. Commission is negotiable in every state. It just rarely gets negotiated, because most sellers only sell once every 7–10 years.

Marketing (aka vendor paid advertising)

Agents almost always ask for a separate marketing budget on top of commission. A standard metro campaign sits between $3,500 and $8,000 and includes:

• realestate.com.au and Domain listings (and premium placements)
• Professional photography and floorplans
• Signboard, brochures, and social media

Premium or auction-heavy campaigns (with video, drone, and upgraded portal placements) can stretch to $10,000–$15,000+. Marketing is paid up-front or deducted from settlement, not contingent on the sale.

Conveyancing and legal

A conveyancer or solicitor prepares the contract of sale and handles settlement. Budget $800 – $2,200 depending on state and complexity, slightly higher in NSW, slightly lower in Victoria.

Lender fees

If you've got a mortgage on the property, your lender will charge a discharge fee to release it at settlement. This typically lands between $150 and $1,500 depending on the lender, and the discharge process itself takes 14–21 days, so it's worth starting early.

Styling, staging, and prep

Optional, but common in the metro markets. Hire staging can run $3,000 – $8,000+ for a 4–6 week campaign. Minor repairs, gardening, and cleaning easily add another $1,000 – $3,000.

Auction fees (if you go that route)

An auctioneer is typically a flat fee of $400 – $1,000, sometimes bundled into the marketing package.

What it looks like all together

For a $1.2m metro sale, a traditional agent campaign often totals:

That's roughly 2.7% – 3.8% of the sale price, not the headline 2%.

How the cost changes by state and city

The single biggest variable is commission, and that moves with location:

• Sydney and Melbourne: the most competitive agent markets, so commission is often lower (1.8% – 2.5%), but marketing budgets and styling spend tend to be the highest in the country.
• Brisbane: commission usually sits around 2.0% – 3.0%. Queensland has a statutory cooling-off period for residential sales, which shapes your timeline more than your budget, and a conveyancer or solicitor is essential for the contract.
• Perth and Adelaide: broadly similar to Brisbane on commission, with marketing campaigns often a little cheaper than the east-coast capitals.
• Regional Australia: commission is typically the highest (2.75% – 3.5%) because there are fewer agents and lower sale volumes, though the dollar amounts can still be smaller on lower-priced homes.

Wherever you are, the percentage is negotiable and the marketing line is the one most sellers overpay on.

Where flat-fee changes the picture

Flat-fee platforms like helm decouple the sale price from the amount you pay. You get the tools an agent campaign uses (professional listing, AI-enhanced photos, offer management) for a fixed fee. On a $1.2m sale, the difference between a flat fee and a percentage commission can be $25,000 – $35,000+ that stays in your pocket, depending on campaign and prep spend.

The trade-off: you stay more involved in the process. Whether that's worth it depends on your time, comfort with negotiation, and how unusual the property is. We break down the three selling routes side by side here.

The honest summary

Don't compare options on commission alone. Compare the total out-of-pocket against what you're getting back in time, expertise, and certainty. An agent earning $30,000 is worth it if they add $60,000 to the final price. A flat-fee platform is worth it if the market is moving and the property broadly sells itself.
