Leafy, family-oriented suburb on the rise above Manly, about 12 km north-east of the Sydney CBD in Northern Beaches Council. Seaforth overlooks Middle Harbour - linked south to Mosman by the Spit Bridge - with views across Sugarloaf Bay to Castlecrag, and Garigal National Park running along its northern border; it was subdivided in 1906 by Henry Halloran and named after Loch Seaforth and Seaforth Island in Scotland. It is a settled residential suburb of 7,384 people (2021 census) with a very high-income profile - median weekly household income of $4,184, more than double the national median of $1,746 - and a strong family base, with 23.1% of residents aged under 15. Buyers and local agents describe a quiet, village-focused pocket of large family homes on generous blocks with harbour and bay views, bushland edges, a good local school and easy access to Manly without its crowds (StMate).

Transport
Seaforth has no railway station - the Northern Beaches peninsula has no train line at all - so public transport is bus-based along the Sydney Road corridor, with city express X services (routes such as 171X, 172X and 173X) running past the suburb on their way over the Spit Bridge, and local routes such as the 141 linking Seaforth with Manly and Frenchs Forest/Austlink. The nearest rail access is across the harbour in the city or on the lower North Shore, and many commuters instead take a bus to Manly Wharf and the ferry to Circular Quay, a popular alternative to road traffic (StMate). Car travel is heavy: the Spit Bridge is the key pinch point at peak times (StMate).
Schools
Seaforth Public School - the NSW government K-6 primary school in the suburb - anchors the local family scene and is a key reason families choose Seaforth; it is the only school physically in the suburb. There is no high school in-suburb: local secondary students are served by Northern Beaches Secondary College Balgowlah Boys Campus, the government boys' high school in adjacent Balgowlah, with other NBSC campuses and independent schools in the wider Manly area. Catholic families previously drew on St Cecilia's Catholic Primary School in adjacent Balgowlah, which Catholic Schools Broken Bay announced in August 2025 would close permanently by the end of that school year (its site becoming the St Paul's Catholic College Years 5-6 campus); St Mary's Catholic Primary School is in Manly, not in Seaforth.
Shopping & Amenities
The Seaforth village shopping district is set off Sydney Road and offers day-to-day services and specialty/niche shops, and it is home to the Balgowlah RSL Memorial Club despite the club's name. Major retail - full-line supermarkets, specialty stores and a cinema - is at Stockland Balgowlah in the immediately adjacent suburb of Balgowlah, while Manly's beaches, Corso and dining strip are a few minutes further on (StMate).
Parks & Outdoors
Seaforth's bushland and harbour setting gives it strong local recreation. Seaforth Oval, a sportsground with playground on Wakehurst Parkway, sits within the suburb, and Garigal National Park runs along the suburb's northern border. The Manly Dam bushland reserve, the large recreation and mountain-biking park around the dam, begins in Manly Vale just across Wakehurst Parkway at the suburb's north-western edge. Tania Park - sportsfields, playground, BBQs and dog areas with sweeping Sydney Harbour views, surrounded by Sydney Harbour National Park trails - lies in adjacent Balgowlah Heights, which borders Seaforth on the southern ridge, and the Manly-to-Seaforth foreshore walk links the suburb to Clontarf, The Spit and Sydney Harbour National Park.
Property Market
The median house price in Seaforth was around ~$3.3M-$3.8M depending on tracker and sales window: Domain reported a Seaforth median house price of $3,327,500 (a 26% rise over five years but a 5.3% drop over 12 months); StMate puts the 4-bed house median at ~$3.55M (mid-2026, -5.3%/yr) with entry-level ~$2.73M and premium ~$5.68M; Allhomes lists a median house sale price of $3,800,000 (Domain; StMate; Allhomes). See our full Sydney property price map for how the suburb compares across the city. Seaforth is a premium harbourside family market of houses on generous blocks (92% of stock), with strong turnover at the top: recent July 2026 sales include 19 Edgecliffe Esplanade at $7.10M, 61 Gurney Crescent at $10M and 4 Ellery Parade at $3.70M, while waterfront icons like 'Anschau House' (73 Seaforth Crescent) list at $7.75M (StMate; Allhomes). Domain and StMate both record a ~5.3% 12-month pullback, an adjustment after five-year growth of 26%, and StMate notes ~43 house sales a year, a 2.9% gross rental yield, and a median household income of $4,184/week - among the highest in Sydney.
New Developments
Limited and leafy - Seaforth is an established, tightly held suburb of family homes where redevelopment is mostly single-dwelling knockdown-rebuilds and alterations, not large-scale projects (microburbs DA listings). There is no town-centre tower development; the village shopping district remains low-rise and the council's planning focus is on preserving the bushland and harbour character around the suburb's edges.
Jobs & Local Economy
Seaforth is a professional commuter suburb: the 2021 census recorded a median weekly household income of $4,184, more than double the national median, and most residents work outside the suburb - in Sydney CBD and North Sydney offices reached across the Spit Bridge, with bus-ferry or car commutes - while Northern Beaches Hospital at Frenchs Forest, the peninsula's 488-bed public hospital, is the major regional employer within about a 10-minute drive. Local employment is limited to the Sydney Road village shops and services, the Balgowlah RSL Memorial Club and small businesses serving the suburb.
