Property Details for 39 Mariner Ave, Seacliff Park
Last Listing description (July 2026)
Set between rolling fairways and the coastline's sparkling edge, 39 Mariner Avenue lands with the kind of freedom that's getting harder to find - a sprawling 625sqm parcel wrapped in leafy calm and primed for a future that thinks bigger.
This is your chance to shape something truly exceptional from the ground up. Whether it's a forever family home with room to breathe, a statement-making architectural showpiece, or a cutting-edge eco retreat designed to blur the line between indoors and out (STCC), this is the sort of blank canvas that invites ambition and rewards vision in equal measure.
And when the plans are done, the lifestyle writes itself.
Morning laps at Seacliff Beach, twilight rounds at Seacliff Golf Club, long walks through Glenthorne National Park, coffee runs to Nest, and sunset sessions at the Seacliff Beach Hotel - all unfolding within minutes of your front door. Add prized zoning for Seaview High School and Seacliff Primary, plus an easy CBD commute, and the lifestyle equation only gets stronger.
Coastal ease, lifestyle prestige, and architectural possibility in perfect alignment - 39 Mariner Avenue is ready to take the lead.
