Let’s explore the five elite suburbs leading the property charts in Sydney’s North Shore this year.

1. Longueville – Harbourfront Luxury with Unmatched Privacy

Median House Price (2025): $6.4 million
Median Apartment Price (2025): Limited stock – approx. $2.8 million
Median House Rent: $2,500/week
Median Unit Rent: $1,300/week

Longueville is the crown jewel of the Lower North Shore. Set on a peninsula with sweeping views of Sydney Harbour, it’s renowned for its ultra-private residences and low-density living. Homes often feature large waterfront blocks, private pontoons, and luxury finishes. Apartments are few, tightly held, and command prestige-level prices due to the suburb’s exclusivity.

It’s zoned for Lane Cove West Public School and is close to top private institutions such as Saint Ignatius’ College Riverview. Crime rates are among the lowest in Greater Sydney. While ferry access and buses offer public transport, most residents commute via car. The walkability score sits around 76, particularly strong near foreshore parks and local reserves.

With only minor development planned, Longueville maintains its serene charm and long-term capital growth potential.

2. Mosman – Timeless Prestige with Iconic Beachfront Appeal

Median House Price (2025): $5.8 million
Median Apartment Price (2025): $2.25 million
Median House Rent: $2,100/week
Median Unit Rent: $1,150/week

Mosman is one of Australia’s most recognisable luxury suburbs - with Balmoral Beach, boutique villages, and historic mansions lining its picturesque streets. The suburb attracts wealthy buyers looking for coastal lifestyle without sacrificing proximity to the city. Apartments here are popular with downsizers and executive renters, pushing unit prices into premium territory.

Mosman Public School is high-performing, and private schools like Queenwood and Redlands are within walking distance. The suburb also scores a high walkability rating of 89. Frequent buses and ferry terminals offer fast links to the Sydney CBD. Low crime and ongoing investments into the Spit Junction and foreshore upgrades keep property demand high.

Whether it’s waterfront luxury or leafy hillside living, Mosman continues to define Lower North Shore prestige.

3. Killara – Grand Estates, Elite Schools and Lasting Value

Median House Price (2025): $3.9 million
Median Apartment Price (2025): $1.4 million
Median House Rent: $1,800/week
Median Unit Rent: $950/week

Killara’s wide streets, golf-course views, and heritage estates make it one of the most desirable Upper North Shore addresses. With a strong community vibe and elite schooling, it’s a magnet for affluent families.

Many homes here sit on oversized blocks with established gardens and elegant architecture. Luxury apartments and townhouses are rising near the station, but remain relatively scarce.

Killara High School is one of the top government schools in NSW. Walkability around the station precinct is improving, currently scoring around 75. Public transport is strong, with Killara Station offering a direct line to Central Station in under 30 minutes. Crime rates are low, and ongoing parkland upgrades are planned near Swain Gardens and Marian Street Theatre.

For families seeking a long-term base, Killara offers generational value and timeless appeal.

4. Wahroonga – Leafy Grandeur with Family-Focused Prestige

Median House Price (2025): $3.85 million
Median Apartment Price (2025): $1.3 million
Median House Rent: $1,750/week
Median Unit Rent: $900/week

Wahroonga is one of the North Shore’s most elegant and spacious suburbs, home to grand Federation estates, prestigious schools, and a peaceful village atmosphere. Large homes dominate the streetscape, often featuring tennis courts, pools, and manicured lawns. Units are more affordable but still command premium prices due to the location.

Wahroonga Public, Knox Grammar and Abbotsleigh deliver strong academic outcomes and are major drawcards. The suburb has a walkability score of 78, especially around Wahroonga Village and the station.

Wahroonga Station provides direct access to the city, while local bus services connect to Hornsby and Macquarie Park. With consistently low crime and tree-lined streets, it’s a top pick for professionals with families.

Planned infrastructure upgrades include pedestrian safety improvements and green space rejuvenation.

5. Cremorne Point – Harbour Views and Blue-Chip Living

Median House Price (2025): $4.9 million
Median Apartment Price (2025): $2.1 million
Median House Rent: $2,200/week
Median Unit Rent: $1,200/week

Cremorne Point offers a rare combination of tranquillity and world-class views. Nestled on a peninsula, it gives residents panoramic vistas of the Harbour Bridge and Opera House. Houses here are tightly held and often feature restored heritage charm blended with modern luxury. Apartments along the foreshore offer equally impressive views and strong rental appeal.

It’s within the catchment for Neutral Bay Public and close to private schools in North Sydney and Mosman. The Cremorne Point Ferry is one of the most scenic commutes in the city. Walkability is excellent with a score of 91, thanks to harbourside trails, parks, and excellent local cafés. Crime is notably low, and the area benefits from council-driven foreshore maintenance and preservation.

It’s one of the Lower North Shore’s best-kept secrets — if you can find a home, that is.
