Mitsubishi Estate Buys Into Mirvac’s $1.3B Sydney Darling Harbour Residential Project 

Japanese giant Mitsubishi Estate has entered a joint venture with Australia’s Mirvac to deliver a Sydney residential project with an expected end value of over A$2 billion ($1.3 billion).

The under-construction Harbourside project at Darling Harbour near the city centre will offer 260 luxury apartments across 48 levels upon completion, the partners said Sunday in a release. The complex will feature 35,000 square metres (376,737 square feet) of premium office and retail space, 10,000 square metres of public open space and a 3,500 square metre waterfront park.

Mitsubishi Estate and Mirvac will be 50:50 development partners and owners for Harbourside’s residential, commercial and retail components, with the ASX-listed builder providing development management services. Mirvac will continue to handle investment management and asset management services on completion, which will take place in stages from 2027.

“This joint venture presents us with a unique opportunity to invest in a flagship mixed-use development that will leave a lasting legacy to the urban landscape of Sydney,” said Yosuke Matsunaga, Mitsubishi Estate’s head of Australia. “This project aligns with our strategy of collaboration with established and trusted local partners to deliver world-class developments in key urban locations.”

Japan Giants Jump In

With its involvement in Harbourside, Mitsubishi Estate expects the cumulative project cost of its Australia portfolio to grow to more than JPY 1.7 trillion ($11.6 billion).

Sydney projects continue to draw keen interest from Japan’s heavyweights, with Mitsui Fudosan acquiring a 66 percent stake in Mirvac’s $1.3 billion 55 Pitt Street office tower development last year and Mitsubishi Estate and Nippon Steel reportedly backing Lendlease’s luxury residential redevelopment overlooking Hyde Park. Mitsubishi Estate’s involvement in Harbourside was first reported by The Australian in August.

Mirvac CEO Campbell Hanan called Harbourside “the final piece of the rejuvenation of Darling Harbour”, where the 1988-era Harbourside Shopping Centre was demolished in 2023 to make way for the new development.

“The project is on track, with construction well-progressed, all major development approvals and milestones achieved, and over A$800 million in residential pre-sales secured,” Hanan said. “We have secured a pre-commitment for our premium-grade waterfront commercial office and have entered into a heads of agreement with a flagship food and beverage operator for a key part of the retail.”

Home Values Perk Up

Sydney’s residential market picked up pace in the second quarter after a slow start to 2025, according to CBRE, as values rose for both houses and units following central bank rate cuts.

The median house value increased 1.9 percent on a quarterly basis and 2.2 percent year-on-year to A$1,526,000 as the median unit value climbed 1.3 percent quarterly to A$868,300, unchanged from a year earlier, CBRE said in its latest report, citing data gathered by CoreLogic.

“There are some counteracting factors, however, which should temper the scale of increase over the remainder of 2025,” the consultancy said. “Listings remain slightly elevated, around 10 percent higher than the decade average in June 2025, and can be expected to rise as the spring selling season approaches.”

Population growth has softened further, with the annual growth rate in New South Wales easing to 1.3 percent in 2024 from 2.1 percent in 2023, the report added. Net overseas migration intake slowed to an annualised 106,700 from a recent peak of 183,000 in September 2023, it said.
