Discover Australia’s most expensive home: a $141.55 million penthouse in One Sydney Harbour, Barangaroo. Explore why this trophy residence redefines luxury living in Sydney.
A New Standard of Luxury Living in Australia
Australia’s ultra-luxury property market has reached a new pinnacle with the historic sale of a penthouse at One Sydney Harbour for an astonishing $141.55 million. This unprecedented transaction not only cements Barangaroo’s reputation as the nation’s most elite waterfront precinct but also places Sydney firmly on the global luxury real estate map.
Located atop the tallest of Lendlease’s three towers at One Sydney Harbour, this off-the-plan residence has become Australia’s most expensive home, setting a benchmark that redefines opulence, exclusivity, and architectural ambition.
A Residence Beyond Compare
The penthouse—purchased by a Chinese-born company director —is no ordinary residence. It spans the top three floors of the tower and merges a premier penthouse with a sub-penthouse to create an ultra-home of exceptional scale and prestige. The total footprint surpasses 1980 square metres, a rare offering even by international luxury standards. From a private rooftop terrace, pool, spa, and gym, to uninterrupted panoramic views of Sydney Harbour, the Opera House, and Harbour Bridge, every element of the residence speaks to a vision of world-class elegance. The property’s price tag also shattered the elusive $100,000 per square metre barrier—an extraordinary achievement for residential real estate in Australia. This residence isn’t just the most expensive home in the country—it is a trophy asset on a global scale.
Barangaroo Stands as the Beating Heart of Australia’s Luxury Real Estate
Where Rarity Meets Reputation
Barangaroo has fast become the epicentre of luxury real estate in Australia. Strategically positioned on Sydney’s northern waterfront, the precinct is a masterclass in urban reinvention, offering architectural brilliance, harbourside views, and a lifestyle that fuses tranquillity with cosmopolitan energy. The One Sydney Harbour towers, designed by Pritzker Prize-winning architect Renzo Piano, are the crown jewels of the precinct. Their sweeping glass facades, sculptural design, and unrivalled vertical privacy make them not only an engineering triumph, but also a magnet for the world’s wealthiest homeowners. With only a handful of residences offering such scale and uninterrupted views, the demand for premium real estate in Barangaroo has soared, driven by scarcity, legacy-grade design, and access to luxury lifestyle infrastructure.Strata Prestige at a Monumental Scale
The cost of maintaining such a residence is equally remarkable. The conjoined penthouse and sub-penthouse carry 6,903 unit entitlements—a reflection of the home’s grandeur and proportion. Strata fees are expected to be among the highest in the country, fitting for a residence that redefines private luxury living on the Sydney skyline.

Central Barangaroo and the Next Billion-Dollar Chapter
Central Barangaroo is the transformative final stage of the Barangaroo precinct—a $5 billion, 5-hectare development that will become Sydney’s newest world-class destination. Positioned between Barangaroo Reserve and Barangaroo South, it will offer a vibrant mix of residential, retail, hospitality, and community uses, all seamlessly integrated with generous waterfront parklands, civic spaces, and cultural amenities.

The precinct will also feature a new entry to the Barangaroo Metro station, enhancing accessibility and connectivity.Shaping a Connected and Sustainable Future
Central Barangaroo will include several hundred new homes, well-located near jobs, transport, and amenities. Around 50 new destinations are planned, offering a premium mix of lifestyle, wellness, luxury, and dining experiences. Cultural and community spaces—such as a gallery, library, or performance venue—will be shaped through community consultation during the design phase.
Buildings will range from four to ten storeys, with architecture by a mix of local and international firms to ensure high-quality, complementary design. Sustainability is central to the vision, with targets for carbon-neutral operations, water recycling, and industry-leading environmental standards.
