Australia’s most expensive homes the definitive 2025 guide

First, what counts as “most expensive”?

Two quick clarifications make the numbers make sense:

• Houses vs. apartments. In Australia, the all-home price record now belongs to an apartment (a three-level penthouse) rather than a freestanding house. Many lists mix the two; both are called out separately so comparisons remain like-for-like. 

• On-market vs. off-market. Most ultra-prime deals never hit a public listing. They trade quietly via a very small circle of agents, advisers and lawyers. Any public figure cited below is either officially lodged (when it settles) or widely reported by multiple trusted outlets.

The records (as at September 2025)

Australia’s most expensive home (any dwelling type)

A$141.55 million — the One Sydney Harbour “super-penthouse” (Barangaroo, Sydney): a three-level residence at the top of Lendlease’s flagship Renzo Piano–designed tower. The buyer, businessman Yan Zhang, settled at A$141.55m, setting the national residential price record. It eclipsed every confirmed house and apartment sale before it. 

Australia’s most expensive house

A$130 million — Uig Lodge, Point Piper (Sydney): a harbourside, Scottish-baronial trophy estate bought by Atlassian co-founder Scott Farquhar in late 2022. This remains the house record (as distinct from the apartment record above). 

Other defining reference points

Fairwater, Point Piper (Sydney): bought in 2018 by Atlassian co-founder Mike Cannon-Brookes for ~A$100m, the first Australian house to crack nine figures and a landmark in this market. (The New Daily)
One Sydney Harbour’s earlier off-the-plan penthouse (separate from the 2025 record) reportedly sold for “$140m+” back in 2019, signalling that ultra-prime apartments would compete head-to-head with harbour mansions. 

On the scoreboard, the apartment record (A$141.55m) sits above the house record (A$130m). Both are in Sydney and both reflect the same truth: absolute scarcity on deep, blue-chip water.

Where the money goes: ultra-prime suburbs and why they dominate

Sydney (NSW): Point Piper and friends

If a small circle is drawn around Point Piper, Vaucluse, Bellevue Hill, Darling Point and parts of the Lower North Shore (Mosman/Neutral Bay), it captures the bulk of Australia’s biggest transactions. In 2025 alone:

• Point Piper deals still set the tone: for example, a Wolseley Road mansion changing hands at A$55m in mid-2025—not a record, but emblematic of the “floor” for best-in-class homes on that street.

• “Wingadal”, the John Symond harbourfront estate in Point Piper, was floated in 2025 with talk of A$200m–$300m—then quietly withdrawn after the owner declined multiple reported offers above $200m. No sale, but a clear signal of where vendor expectations sit for once-in-a-generation properties.

Melbourne (VIC): Toorak, Brighton and the state record chase

Melbourne’s prestige heart is Toorak, with Brighton anchoring the beachfront trophy set. Two data points from the past year:

• Coonac, Toorak (Paul Little’s historic estate): widely reported as north of A$100m and variously guided at A$115m–$135m, which would be a Victorian record and one of the largest-ever house deals nationally. (Industry chatter has the result nearer the low end of that guidance.)

• A separate Toorak mansion sale “close to A$70m” topped Melbourne’s 2024 ladder, while Brighton’s suburb record climbed to ~A$40m in July 2025. 

Brisbane & the Gold Coast (QLD): new money, new highs

Queensland’s prestige market keeps surprising to the upside:

• Brisbane’s house record reset to A$23m in 2024 (Ascot), while the state’s biggest 2024 sale was a Palm Beach beachfront at A$40m—a new Queensland benchmark. 

Perth (WA): Western Suburbs consistency, occasional spikes

Perth’s “Golden Triangle” (Peppermint Grove, Dalkeith, Cottesloe) remains the state’s prestige anchor. Recent top sales sit in the eight-figure mid-teens, with Peppermint Grove and Mosman Park trades leading the 2024–25 period (e.g., A$14.5m in Peppy Grove; A$22m in Mosman Park for the 2023–24 financial year’s top line). 

Australia’s ultra-prime “league table” (illustrative highlights)

Below is a narrative list of notable trophy results to help map the field. (It is not exhaustive; off-market deals are frequent and not all prices are fully disclosed.)

• One Sydney Harbour super-penthouse, Barangaroo (Sydney) — A$141.55m (apartment, 2025). National residential price record. Buyer: Yan Zhang. 

• Uig Lodge, Point Piper (Sydney) — A$130m (house, 2022). National house price record; buyer: Scott Farquhar.

• Fairwater, Point Piper (Sydney) — ~A$100m (house, 2018). A watershed moment for the market; buyer: Mike Cannon-Brookes.

• One Sydney Harbour earlier penthouse sale — A$140m+ (apartment, reported 2019), underscoring that top-tier sky-homes compete directly with waterfront mansions.

• Point Piper (Wolseley Rd) — A$55m (house, 2025). One of the year’s larger confirmed Sydney trades to date.

• Coonac, Toorak (Melbourne) — reported A$115m–$135m range (house, 2024–25). Credible reporting puts the outcome near the lower end; either way, a Victorian record-buster.

• Toorak mansion, Macquarie Rd — “close to A$70m” (house, 2024), topping Melbourne’s 2024 list at the time.

• Brighton beachfront — about A$40m (house, 2025), a suburb record.

• Queensland records — A$40m Palm Beach (state record, 2024); A$23m Brisbane (Ascot) house record in 2024.

• WA recent toppers — A$14.5m Peppermint Grove (2024–25), A$22m Mosman Park (2023–24).

What makes these homes this expensive?

• Absolute scarcity. True deep-waterfront blocks on Sydney Harbour—or north-facing blocks with privacy and protected view corridors—are almost impossible to replace. Apartments that assemble multiple whole floors at the very top of a globally recognised tower create a similar scarcity in the sky. That’s why the past two national records were in Barangaroo and Point Piper.

• Land + line of sight. It isn’t just the postcode; it’s the geometry. Trophy buyers pay for outlooks that are legally and physically hard to obstruct: Opera House/Harbour Bridge vantages, ocean horizons, deep river bends, or uninterrupted city panoramas. Projects like One Sydney Harbour are literally designed to engineer those view cones.

• Provenance. The name of the house (Fairwater, Uig Lodge, Coonac), the architect’s signature, a celebrity owner, or a place in the city’s story can add millions. These estates are part home, part cultural artefact. 

• Amenity density. Once prices rise into ultra-prime territory, the specification list becomes otherworldly: boat facilities, commercial-grade kitchens, wellness floors, cinema rooms, bulletproof glazing, subterranean garaging, professional security. The “hotelisation” of private homes—spa, gym, staff back-of-house—ramps up fast at this level. (You can see this in the published inventories for top Toorak and Point Piper listings.) 

• Privacy and process. The ability to transact off-market, with compliance and confidentiality handled by a seasoned team, can be part of what the buyer is paying for—especially for global families who need speed, discretion and certainty.

Who buys Australia’s priciest homes?

• Local tech and finance founders/executives. The Atlassian co-founders (buyers at Fairwater and Uig Lodge) defined a new ceiling for Sydney houses. 

• International entrepreneurs and capital allocators. High-net-worth buyers treating Australia as a lifestyle “safe haven” with rule-of-law, strong schools, and relatively low geopolitical temperature. Editors in Sydney and Brisbane have tracked this cohort for years.

• Resource and property families. Especially in Perth and Brisbane/Gold Coast, where wealth sources map to local industries.

How the deals actually get done

• Off-market first, public if needed. Owners of generational assets prefer quiet, targeted campaigns. A public listing is often a second step if a whisper campaign fails to find the number.

• Long lead times. The top end can simmer for months (or years). “Wingadal” is a good example: listed, delisted, relisted, and in 2025 withdrawn again—despite press reports of offers over A$200m. It’s a reminder that a vendor’s reservation price can be higher than a hot market’s clearing price.

• Structures for speed. Top buyers have entities and debt lines ready, advisers on call, and a tolerance for non-standard settlement terms (e.g., rent-backs, staged handovers, discreet early access for works).

• Valuation feels… different. At this level, classic “comparables” barely exist. The small handful of truly like-for-like properties are heavily adjusted for view plane, frontage, build quality, heritage constraints, and waterfront utility (deepwater mooring vs. tidal shallows, for instance). One Sydney Harbour’s three-level penthouse is, by definition, a one-of-one. 

Why Sydney keeps winning the national records

• Deep natural moat: Sydney Harbour and the ocean cliffs form a one-in-the-world canvas.

• Global brand: For overseas buyers, “Sydney Harbour” is a recognisable asset class.

• Stock quality: The east’s harbour streets (Wolseley Rd, Wentworth Place, etc.) and new-generation towers (Barangaroo, Crown/One Barangaroo) deliver a concentration of AAA product.

• Momentum and money: Every new benchmark resets vendor psychology for the next. (You can literally see this in how eight-figure guidance ranges moved after Fairwater ~A$100m, then Uig Lodge A$130m, then the A$141.55m Barangaroo settlement.)

Melbourne’s different—but it’s catching up

Where Sydney leans on waterfronts, Melbourne’s prime story is Toorak’s land, privacy and European-style estates with exceptional gardens and architecture. The Coonac headlines (low-nine figures) show the gap to Sydney narrowing at the very top, and Brighton’s beachfront comp (≈$40m) underscores that bayside trophy demand is real.

Brisbane, the Gold Coast and the case for Queensland

Queensland’s case is simple: lifestyle + relative value + supply limits. When Brisbane’s (ASX:BBL) house record is A$23m and the Gold Coast can print a A$40m beachfront deal, the result is significant house and beach value at a discount to Sydney’s harbour. Momentum in 2024–25 suggests more state records could fall as expats and interstate capital keep buying.

Western Australia: fewer trades, strong medians, occasional fireworks

WA’s ultra-prime market is smaller in count but rich in quality—the Western Suburbs’ estates, river frontages and Indian Ocean views are perennial draws. Annual “top ten” lists often cluster around A$10m–$20m+, with Peppermint Grove repeatedly crowned the priciest median suburb and individual one-offs (e.g., Mosman Park at A$22m) setting the yearly high. 

A short catalogue of standout homes & sky-homes

Sydney trophy houses

• Uig Lodge, Point Piper — National house record (A$130m). A rare marriage of harbour position, provenance and land size. 

• Fairwater, Point Piper — The first Australian home to clear A$100m, its compound scale and history are unmatched.

• Wolseley Road collection — A perennial pipeline of eight-figure deals; A$55m examples still transacting in 2025.

Sydney sky-homes

• One Sydney Harbour super-penthouse — A$141.55m national record. Three levels, private views, Renzo Piano design.

• Earlier One Sydney Harbour penthouse (2019) — reported north of A$140m off the plan, foreshadowing 2025’s record.

• Crown’s One Barangaroo — multiple sales rumoured/confirmed north of A$80m–$100m; creates an alternative ultra-prime address beside Barangaroo.

Melbourne grand estates

• Coonac (Toorak) — A long-guarded heritage estate and a new-era price; look to this as a benchmark for Victorian blue-chip.

• Macquarie Rd (Toorak) — Near-A$70m sale in 2024, illustrating the depth of seven- and eight-figure demand.

• Brighton beachfront — About A$40m in 2025; new suburb high and a reminder that beachfront remains Australia’s other great luxury frontier. 

Queensland & WA headliners

• Palm Beach, QLD — A$40m beachfront in 2024, a state record; Brisbane/Ascot at A$23m.

• Mosman Park, WA — A$22m (2023–24), with Peppermint Grove repeatedly turning in high-teens results.

Frequently asked questions about Australia’s most expensive homes

Are apartments really overtaking mansions?

At the very summit, yes—because the best new-build penthouses can manufacture absolute scarcity: multiple whole floors, private lifts, ultra-secure access, panoramic view corridors no house can match, and hotel-level amenity. That’s how the A$141.55m Barangaroo sale happened. Houses still dominate the top fifty, but the outright record is now a sky-home.

Do vendors actually get their dream numbers?

Sometimes. Often they wait. The “Wingadal” saga shows that even with multi-hundred-million chatter, the owner can simply say no—and stay put until the next cycle. 

Why do so many records cluster in a handful of streets?

Because position (on water or perched above it), protection (planning setbacks, view cones), and prestige (a street’s “brand”) all compound. That’s Wolseley Road, Wentworth Place, and in Melbourne, St Georges Road/Macquarie Road/Albany Road equivalents.

Are prices peaking or pausing?

Luxury is its own weather system. Rate cycles and risk appetite matter, but supply at the very top is fixed. When a new headline deal lands (A$140m+), it resets the negotiating frame for every comparable property.

Buying (or just understanding) the ultra-prime market: a field guide

• Method: Follow the settlements, not just the headlines. Off-the-plan “records” are interesting; settled numbers are definitive. That’s why the Barangaroo A$141.55m settlement matters so much—it’s not just a contract price, it’s done.

• Method: Read across categories. A$50m–$80m houses and A$80m–$140m penthouses speak to different buyer needs. A family that wants a boat shed and lawn will still pick Point Piper over Barangaroo.

• Method: Understand how guidance “ranges” work. A Toorak estate might be guided at A$115m–$135m and transact near the low end. That doesn’t negate the headline; it refines it. The point stands: Melbourne now has credible nine-figure comps. 

• Method: Don’t over-index on any one suburb median. Ultra-prime is about outliers, not medians. Perth’s medians (Peppermint Grove, Dalkeith, Cottesloe) are high and rising, but the top single sales jump around as rare stock surfaces.

The pipeline: what to watch in late-2025

• Fresh Point Piper stock: whisper campaigns keep circling waterfronts near Fairwater and Uig Lodge. After the Barangaroo super-penthouse settled, expect more sky-home ambitions to surface.

• Toorak renovations and estates: blue-chip, move-in-ready properties command a serious premium over rebuild projects—watch guidance for fully executed homes following Coonac’s halo.

• Queensland momentum: cashed-up interstate and expat buyers keep pressing the Gold Coast and Brisbane riverfront/oceanfront. The leap from A$23m (Brisbane) to A$40m (Gold Coast) suggests further headroom. 

• Western Australia’s one-offs: the right riverfront in Peppermint Grove/Mosman Park could easily challenge state highs again.

Why these homes matter (beyond the wow factor)

• They set pricing gravity. A single $100m+ settlement changes how banks, valuers and vendors think about everything one rung down the ladder.

• They shape the city. When apartments break records, it legitimises density done exceptionally well; when estates break records, it helps preserve gardens and heritage buildings (because demolition becomes economically irrational).

• They signal global demand. Record prices in Sydney or Melbourne tell you something about capital’s view of Australia’s stability, security, healthcare, schooling and lifestyle.

Quick reference: the headline numbers you’ll be asked about

• National residential price record (all dwelling types): A$141.55m, One Sydney Harbour three-level penthouse (Barangaroo), 2025, buyer Yan Zhang.

• National house price record: A$130m, Uig Lodge, Point Piper (Sydney), 2022, buyer Scott Farquhar.

• New South Wales touchstones: Fairwater ~A$100m (2018); multiple Wolseley Rd trades A$50m+ in 2025; Wingadal unsold but tested at A$200m+ price talk. 

• Victoria touchstones: Coonac reported A$115m–$135m (2024–25); separate Toorak result near A$70m; Brighton suburb record about A$40m. 

• Queensland touchstones: Palm Beach A$40m (state record, 2024); Brisbane/Ascot A$23m (house record, 2024).

• Western Australia touchstones: Peppermint Grove A$14.5m (2025), Mosman Park A$22m (2023–24).

Methodology & caveats

• Confirmation beats chatter. Wherever possible this guide relies on settled figures and multiple reputable sources (Domain, realestate.com.au, major mastheads). Some ultra-prime trades are guided or reported at ranges; where that’s the case, it is stated and the reporting cited.

• House vs. apartment categories are explicit. The A$141.55m Barangaroo number is a home record; the A$130m Uig Lodge number is a house record. Keeping those separate avoids confusion.

• Markets move. Sydney’s top end can change in a single weekend. A withdrawn listing today can be a record tomorrow (and vice-versa). Ultra-recent items like Wingadal are flagged so their status can be tracked.

Final word

Australia’s trophy property market is small, opaque, and dazzlingly expensive—by design. Sydney’s harbour mansions and sky-homes write the national records; Melbourne’s Toorak estates are pushing decisively into nine figures; Queensland’s beachfronts now carry prices that would have sounded fanciful a decade ago; Perth’s Western Suburbs provide consistent, high-spec family compounds with occasional headline fireworks.

What ties the lot together isn’t just wealth. It’s scarcity—of outlook, of frontage, of privacy, of story. That’s why a penthouse can outsell a palace; why a Point Piper reserve commands reverence; why a Toorak name like Coonac can set a state buzzing; and why a Gold Coast beachfront can write a new state record. In ultra-prime Australian real estate, the rarest thing of all is the right thing in the right place. Pay attention when it appears—because when it’s gone, it’s gone.
