One of Australia’s biggest residential property transactions of 2025 has seen an approximately $150 million sale of six houses and two unit blocks across 20–30 Wilberforce Avenue[i] and 33–37 Dover Road, Rose Bay to a private buyer.

Located in one of the Eastern Suburbs’ most prestigious neighbourhoods, this rare opportunity represented a once-in-a-generation opportunity in tightly held Rose Bay. The turbo-charged sale was managed by Ric Serrao, Principal of Raine & Horne Double Bay | Bondi Beach, along with Alex Lyon, Paul Langsam and Dean Power.

Angus Raine, Executive Chairman of Raine & Horne, praised the flagship Raine & Horne Double Bay | Bondi Beach team for its high-octane dealmaking achievement.

“Ric and his team aren’t consistently our best-performing office for no reason,” Angus said. “Coordinating a sale of this magnitude that includes the sale of multiple residential properties under separate ownership, and securing unanimous vendor agreement, is a complex achievement.

“It requires exceptional negotiation skills and relationship management, which Ric and his team have in spades.”

Angus added, “I’d like to congratulate Ric, Alex, Paul, and Dean on this wonderful achievement, which underscores the culture of collaboration within our flagship Double Bay | Bondi Beach office and the strength of the Raine & Horne brand.”

The 20–30 Wilberforce Avenue holding, listed by Dean Power and Paul Langsam[ii], comprises five lots with a combined 2,939.5 sqm landholding and a premium north-west aspect offering potential harbour views.

With a R3 Medium Density Residential zoning, the combined site could benefit from recent planning reforms allowing a six-storey development with a 22-metre height limit and a 2.2:1 FSR (Floor Space Ratio). In combination these factors could deliver a potential GFA (Gross Floor Area) of approximately 6,466.9 sqm*.

But wait, there's more. Under the Infill Affordable Housing provisions, there the potential for up to a 30% increase in FSR and height, potentially yielding around 8,407 sqm of GFA if approved.

Meanwhile, the Dover Road properties include a four-bedroom home at 33 Dover Road, an older residence on an 847 sqm block at 35 Dover Road, and a boutique apartment block of four units at 37 Dover Road, together forming part of the broader development offering that attracted plenty of attention.
