St Huberts Island is a compact canal community on Brisbane Water, and its two streets tell two quite different stories. Helmsman Boulevard is the island’s absolute waterfront boulevard, lined with private jetties and open-water views. Sirius Street sits one row back, a quieter family street a short stroll from the shoreline. Both share the same schools, boat ramp and Central Coast amenities, so the choice comes down to budget and how close you want the water. The suburb median house price of $1,925,000 is a useful baseline for both.
Waterfront Positioning and Everyday Lifestyle
On Helmsman Boulevard, the water is effectively the front garden. Listings lean on phrases like absolute waterfront and open water views, and 51 Helmsman Blvd pairs a private jetty and pontoon with a new boat ramp, while plenty of other homes carry their own slipway. One north-facing home is described as what people picture when they think of real waterfront living, with uninterrupted open water stretching out in front. Sirius Street offers a softer version of the same lifestyle. It is marketed as a short stroll to the waterfront, and its appeal turns inward to at-home entertaining, with a heated inground pool, an outdoor kitchen and a covered entertaining area at 10 Sirius St. Both streets feed the same island rhythm of boating, kayaking, stand-up paddleboarding and fishing in the canals, plus easy walks and bike rides around the island.
Price, Value and What Your Budget Buys
Helmsman Boulevard carries a published street median sale value of $2,720,000 and a median rent of $1,035 per week. Recorded sales run from a $790,000 duplex at 1/65 Helmsman Blvd up to $3,600,000 for a five-bedroom home at 18 Helmsman Blvd on a 667 m² block, which works out to about $5,397 per square metre. Sirius Street has no published median because transactions are too few, so its value story is told through individual sales: 10 Sirius St sold for $1,675,400 on a 793 m² block, 15 Sirius St for $1,350,000 in 2026 and 8 Sirius St for $1,350,000 in 2021. On its larger, family-sized blocks, such as the 793 m² lot at 10 Sirius St, the rate works out to roughly $2,113 per square metre, well below Helmsman’s premium waterfront rate. Against the island’s shared median of $1,925,000, Helmsman sits clearly above and Sirius offers a lower entry point. Growth on Sirius has been strong, around 74% at 10 Sirius St over nine years and about 108% at 15 Sirius St over eight.
Streetscape, Character and Community
Helmsman Boulevard is the larger and more visible of the two streets. Its 129 properties, mostly houses, are 90% owner-occupied, and the stock skews larger, elevated and modernised, with recurring homes of four or five bedrooms, multiple bathrooms and generous garaging. The street also changes hands steadily for a waterfront address, with a 73.9% average turnover, roughly once every 13.5 years. Sirius Street is far smaller and more tightly held: 11 houses at 80% owner-occupancy, with an established, leafy feel and family homes built around pools, alfresco entertaining and landscaped yards on mixed but generous blocks such as 793 m² and 883 m². Both streets sit inside a small, high-ownership community. The suburb counts 1,080 residents, an average age around 58 and 87.3% owner-occupancy, and Homely rates the island 4.6, summing it up as a groovy island paradise.
Schools and Family Practicalities
There are no schools on the island itself, but both streets share the same catchment. The primary school is Empire Bay Public School, and secondary students head to Brisbane Water Secondary College, with its Umina Campus for Years 7 to 9 and Woy Woy Campus for Years 10 to 12. Helmsman Boulevard is a 16-minute walk from Empire Bay Public School, the closest school to the street, and an 11-minute drive from the Umina Campus. Sirius Street is a 6-minute drive from that primary and a slightly shorter 10-minute drive from the Umina Campus, and it sits notably closer to the Woy Woy cluster: Woy Woy Public School is a 13-minute walk and the Woy Woy secondary campus a 17-minute walk. Private and independent options nearby include Coast Christian School and Central Coast Grammar School.
Getting Around and Nearby Amenities
Both streets share a single road in and out of the island, over the Daleys Point bridge onto St Huberts Road, so access is identical and car-first. Busways Routes 59 and 64 run along the Daleys Point and St Huberts Road corridor, and Woy Woy station is about a 10-minute drive, around 9 km by road, for trains. The Ettalong Wharf ferry reaches Palm Beach in about 35 minutes, and Sydney is around an hour and 20 minutes by car. The island is residential-only, so Ettalong Beach, Umina and Woy Woy are roughly a 5-minute drive for cafes, restaurants, markets and beaches. Helmsman Boulevard adds Helmsman Boulevard Reserve on the street itself, and the community boat ramp at Luderick Avenue serves everyone.
Conclusion
The trade-off is simple. Helmsman Boulevard suits buyers who want absolute waterfront living, private boating infrastructure and open-water views, and who are comfortable with its higher price point. Sirius Street suits buyers who want the same island lifestyle at a lower entry point, on larger, quieter near-water blocks a short stroll from the shoreline. Both streets share the island’s schools, transport, boat ramp and surrounding Central Coast amenities. In the end, the decision rests on the size of the budget and the strength of the preference for water at the doorstep, and either way you are buying into a tightly held, owner-focused waterfront community.
