A sprawling 4400 square metre waterfront property in Rose Bay has quietly hit the market, with industry insiders suggesting it could potentially surpass Australia’s current $130 million house price record.
The exceptional holding at 754-760 New South Head Road represents one of Sydney Harbour’s most prized residential sites, combining two residences, recreational facilities, and what many consider the suburb’s finest harbour views.
The property has deep ties to Australian medical history, having been in the Dan family for over four decades. Records show Adrienne Dan, wife of renowned neurosurgeon Professor Noel Dan AM, purchased the beachfront portion for $1.03 million in 1983. Professor Dan’s groundbreaking epidemiological research into head injuries was instrumental in introducing random breath testing to NSW in 1982, a public health initiative that has saved countless lives.
What makes this site particularly attractive to potential buyers is its rare combination of scale and location. The 4400 square metre block comprises five separate titles and boasts uninterrupted views towards the Harbour Bridge, along with direct beach access and dual street frontages.
The family’s decision to market the entire consolidated site marks a significant shift from previous attempts. In 2023, part of the property was offered separately, creating an oddly-shaped 3300 square metre block that may have deterred potential buyers despite carrying an $85 million price guide.
The current offering includes an additional 1029 square metre parcel featuring a Victorian-style residence, which the family acquired in 1986 for $629,000. This portion, registered under art gallery owner Sally Maree Dan-Cuthbert (Professor Dan’s daughter), provides crucial street-to-beach access and dual driveway options.
Property market observers note the site’s potential has long been recognised. The block was previously owned by advertising executive John Singleton before the Dan family’s purchase. Initial market testing occurred in 2017, coinciding with significant movements in Sydney’s luxury property sector.
The timing appears strategic, following recent record-breaking sales in nearby Point Piper. Atlassian co-founder Scott Farquhar’s $130 million sale of the Elaine estate in October 2024 has reset expectations for Sydney’s waterfront property market.
Sales agents Paul Biller of Biller Property and Joshua Punin of Biller Projects are managing the off-market listing, with sources indicating developer interest has already materialised into formal offers.
The site’s development potential appears substantial, particularly given recent planning precedents for large waterfront parcels in the eastern suburbs. However, the property’s heritage significance and community value as one of Rose Bay’s last substantial private waterfront holdings may influence future development considerations.
For Rose Bay residents, the sale represents the end of an era, as the Dan family’s stewardship of this prime harbourfront land spans more than 40 years of local history.
