St Huberts Island is a compact, canal-lined island on Brisbane Water, and its two signature streets offer two different takes on the same waterfront life. Helmsman Boulevard is the larger, boating-led street that greets you at the bridge. Mainsail Avenue is the smaller, more uniform premium street nearby. Both share the island’s schools, transport and amenity radius, so the real differences sit in streetscape, stock and price.
Streetscape and Character
Helmsman Boulevard is the island’s big street. Domain’s street profile counts 129 properties, mostly houses with two units and one other, and a 90% owner-occupied split. That scale comes with variety: sampled blocks run from about 483 to 693 square metres, and the listing language keeps returning to boating. 53 Helmsman Boulevard pairs a brand-new jetty and boat ramp with direct waterway access, while 105 Helmsman Boulevard is pitched as turnkey coastal living with deep-water mooring and a jetty.
Mainsail Avenue is the compact counterpoint. It holds 37 properties, all houses, with an 85% owner-occupied split, and Domain describes a consistent premium character of two-storey, double-brick homes. Blocks sit more uniformly in the mid-to-high 600s square metres: 19 Mainsail Avenue is a single-level waterfront on 691 square metres, while 33 Mainsail Avenue sits on 696 square metres. Helmsman offers scale and a wide variety of waterfront configurations, while Mainsail offers a tidier, more predictable premium streetscape.
Property Prices and Market Position
Helmsman Boulevard has a citable street median of $2,622,000 and a median rent of $1,060 a week. Recent sales run a broad band. 18 Helmsman Boulevard sold for $3,600,000 in June 2025, a five-bedroom home on 667 square metres, while 77 Helmsman Boulevard sold for $1,400,000 on a 483-square-metre block. The premium end tracks to waterfront homes with improved boating facilities.
Mainsail Avenue trades in a tighter band. Domain puts the street range at $1.97 million to $2.34 million, and recent results cluster accordingly. 19 Mainsail Avenue sold for $2,150,000 on 691 square metres, and 25 Mainsail Avenue sold for $1,970,000 in April 2025. The suburb median is about $1,950,000, up 7.29% over 12 months. Helmsman offers a wider range of entry points and a higher ceiling, while Mainsail reads as a predictable upper-mid premium band.
Transport and Accessibility
Transport is broadly a shared story. Woy Woy railway station is roughly a 10-minute drive with direct rail to Sydney, according to the St Huberts Island community site, which also notes Sydney CBD sits about 40 kilometres away by sea and nearly 100 by road or rail. The Ettalong Wharf ferry crosses to Palm Beach in about 35 minutes. Busways runs the island service, with routes 59, 64 and 5364 offering boarding points within about a kilometre.
Helmsman’s one differentiator is position. The island’s single low bridge from Daleys Point lands onto Helmsman Boulevard, and the Bridge Reserve at the street’s entry adds a little green space. That gives Helmsman residents the most direct mainland entry and exit.
Schools and Education
Schools do not separate these streets. Both fall in the same catchment: Empire Bay Public School for primary, about a 16-minute walk away, with an ICSEA of 1,039 and 426 students, and Brisbane Water Secondary College Umina Campus for secondary, about an 11-minute drive, with an ICSEA of 966 and 787 students. There are no schools on the island itself, but private options such as Coast Christian School, St John the Baptist Catholic Primary School and Green Point Christian College sit about 11 to 12 minutes away by car. Families on either street share the same short-drive schooling network.
Lifestyle and Amenities
Day to day, the two streets share one lifestyle. Ettalong is the island’s closest neighbour, and Umina and Woy Woy sit less than five kilometres away, which puts beaches, markets and everyday services a short drive from either street. Eight parks cover about a quarter of the island’s area, and the water is the main event, with kayaking, stand-up paddleboarding and fishing in the canals, plus boating and sailing on Brisbane Water, as the suburb profile describes.
The difference is outlook. Helmsman’s listing language keeps returning to north-facing waterfront, while Mainsail’s waterfront homes lean sunny and sheltered, with 21 Mainsail Avenue’s north-facing deck capturing the winter sun and 6 Mainsail Avenue described as an absolute waterfront home with stunning views. The choice comes down to which view you prefer.
