St Huberts Island is not the kind of place where buyers pore over dozens of streets. The island has about 30 of them, it covers barely 0.6 square kilometres, and homes trade so slowly that some streets average 13 to 20 years between sales. When a listing does appear, you are choosing between two quite different versions of waterfront living.
Discovery Street and Sirius Street sit on opposite sides of the island and represent two distinct takes on the canal-estate lifestyle. One leans into family resort living centred on the home and garden. The other is built around direct boating and water access.
Location and Setting
St Huberts Island is connected to the mainland by a single road via Daleys Point bridge, and the island covers roughly 0.6 km². No street is more than a minute’s drive from any other.
Discovery Street sits on the eastern side, near Long Arm Parade and Barracouta Avenue. Sirius Street is on the western side, with water at both ends. Both are a five-minute drive from Ettalong Beach, Umina, and Woy Woy.
Property Values and Growth
Discovery Street has a median sale value of $1,437,000. Sirius Street has no reported street median, since its 11 houses yield fewer transactions to calculate from than Discovery Street’s 19.
The highest Discovery Street sale is 16 Discovery Street at $1,780,000, a five-bedroom home on 696 m² that previously sold for $237,000 in 1998. On Sirius Street, the top sale is 10 Sirius Street at $1,675,400 (up from $965,000 in 2017), with 13 Sirius Street at $1,500,000 and 15 Sirius Street at $1,350,000 (up from $650,000 in 2018).
Both streets sit below the suburb median of $1,925,000 and below premium waterfront streets like Cuttlefish Parade at $2,753,000 and Helmsman Boulevard at $2,622,000. Suburb-wide, compound growth is 6.8% per year over four years, with house values rising 19.72% over five years.
Lifestyle and Recreation
Discovery Street is geared toward home-and-garden family living. Number 16 exemplifies the character: a swimming pool, pool house, office pod, outdoor entertaining with built-in BBQ, fire pit, and solar energy. Listings position the street for growing families. No Discovery Street listing mentions canal frontage, a jetty, or boating infrastructure.
Sirius Street is built around boating and water access. A council-owned boat ramp on Luderick Avenue sits a short walk away. The street has water at both ends, 15 Sirius Street is roughly 50 metres from the water’s edge, number 13 has a drive-through garage suited to boat storage, and 10 Sirius Street offers deep waterfront with a jetty.
Both streets share the island lifestyle: kayaking, stand-up paddle boarding, fishing, and leisurely walks and bike rides around the island. Eight parks cover 24.9% of the island. Brisbane Water National Park is a short drive away for bushwalking trails. Canal revitalisation works announced in December 2025 will improve waterway amenity across the island.
Streetscape and Character
Discovery Street has 19 houses, 85% owner-occupied. Homes tend toward single-level floorplans in immaculate condition, with resort-style features shaping the character. A unique landmark is the 1788 First Fleet landing obelisk in the Long Arm Parade reserve. Typical blocks range from 685 to 703 m².
Sirius Street is more intimate, with 11 houses and 80% owner-occupancy. Block sizes vary widely (341 to 793 m²), and the architectural mix spans single-level brick-and-tile homes, two-storey family homes, and smaller dwellings. Water proximity at both ends, drive-through garages, and the nearby boat ramp define the streetscape.
Both streets share the same demographic: population 1,080, median age 58, a mature community of primarily couples. St Huberts Island is a 1970s canal estate with limited subdivision potential. Recent development applications lodged across the island are overwhelmingly for alterations and additions to existing homes, consistent with an established, low-turnover community.
Schools, Transport, and Everyday Practicalities
These are functionally identical across both streets.
Both fall into Empire Bay Public School for primary (about a six-minute drive) and Brisbane Water Secondary College Umina Campus for secondary (10 to 11 minutes by car, with Sirius Street marginally closer). Private school options include Central Coast Grammar School in Erina Heights, St John the Baptist Catholic Primary School in Woy Woy, and Green Point Christian College, all roughly an 11-minute drive. No schools exist on the island.
Both streets have zero public transport stops within 1,500 metres. Busways routes 59, 64, and 5364 board about one kilometre away. A ferry from Ettalong to Palm Beach and the 80-minute drive to Sydney serve the island. Both streets are equally car-dependent.
There are no shops or commercial amenities on St Huberts Island itself. All groceries, cafes, restaurants, and retail require a short drive to Ettalong Beach, Umina, or Woy Woy.
Conclusion
Discovery Street delivers resort-style family living with a poolside entertaining focus, strong long-term price appreciation, and a heritage connection to the First Fleet landing. Sirius Street offers a more intimate, water-access-oriented lifestyle with boating infrastructure at a slightly lower entry price.
Neither is objectively better. Discovery Street suits families who want the holiday at home. Sirius Street suits boating enthusiasts, downsizers wanting water proximity without a waterfront price tag, and buyers who value a smaller, more intimate street. Both share tightly held, strong-growth island fundamentals. Given how rarely properties trade here, buyers interested in either street should be ready when a listing appears.
