St Huberts Island is one of the Central Coast’s most tightly held waterfront enclaves, and two of its best-known streets, Cuttlefish Parade and Mainsail Avenue, represent distinct entry points into the island lifestyle. Here is a clear, evidence-based picture of what each street offers.
Price and Value: The Premium Question
Cuttlefish Parade commands a clear premium. Recent sales span $2,500,000 to $4,250,000, with estimated values from $2,327,000 to $4,229,000. Mainsail Avenue sits in a more accessible band: recent sales from $1,970,000 to $2,600,000, with estimated values from $2,295,000 to $2,432,000.
For comparable property sizes, Cuttlefish Parade tends to run $300,000 to $500,000 or more above Mainsail Avenue. The top recorded sale on Mainsail ($2,600,000 at 13 Mainsail in 2023) sits well below 29 Cuttlefish Parade at $4,250,000.
Both streets have rewarded long-term holders. 13 Cuttlefish Parade sold for $1,260,000 in 2015, while 29 Mainsail Avenue changed hands at $1,120,000 in 2017. Island-wide, houses recorded a 19.72% median value increase over five years to July 2026. The suburb median sits at $1,925,000 across 18 sales in the past 12 months. Both streets sit above that benchmark, with Cuttlefish Parade substantially so.
Streetscape and Character: Cul-de-Sac Prestige versus Architectural Variety
Cuttlefish Parade is a cul-de-sac, and that layout defines its character. With no through traffic, the street has an intimate, settled feel. Listings describe it as “dress circle” and “one of the Islands most prestigious streets.” 26 Cuttlefish Parade sits on “one of St Huberts Island’s widest and most private canals,” while 32 Cuttlefish Parade offers 36.8 metres of direct waterfront frontage on “crystal clear waters and an amazing white sandy beach.” Lot sizes range from 650 to 854 square metres.
Mainsail Avenue is a through-road with greater architectural variety. Original 1980s double-brick homes sit alongside modern renovations, creating a more organic streetscape. 30 Mainsail Avenue delivers “uninterrupted and expansive views of Shelter Cove,” while 11 Mainsail Avenue brings a “sunny northerly aspect” with “amazing sunsets.” A recurring listing theme is “potential to add value,” signalling more original-condition homes ready for personalisation. Lot sizes cluster between 659 and 696 square metres.
Lifestyle and Occupancy: Permanent Retreat versus Holiday Rhythm
Both streets deliver the signature St Huberts Island waterfront lifestyle: boating, kayaking, fishing, and direct canal access from private jetties and slipways. The difference lies in who is home on any given weekend.
Cuttlefish Parade is tightly held with strong owner-occupier signals. The cul-de-sac layout and premium positioning attract permanent residents who value privacy and a settled community. A holiday rental at 12 Cuttlefish Parade (from $279 per night) exists but is less prominent in the street’s identity.
Mainsail Avenue has a more varied rhythm. 18 Mainsail Avenue was “a part-time residence for its entire lifetime,” held by one family for 47 years, and the street hosts a premium holiday rental at $695 per night with private jetty, north-facing pool, and fire pit. This blend of permanent residents, weekenders, and short-term stays creates a more transient feel during holiday periods.
Island-wide community life is shared by both streets. The St Huberts Island Residents Association, founded in 1976, publishes a quarterly newsletter and runs an annual St Huberts Day BBQ at Long Arm Reserve drawing up to 200 residents. The $5 annual subscription has not changed since 1976. Census data confirms an established owner-occupier profile: median age 58, 87.3% owner-occupied, and predominantly Professionals and Managers.
Practicalities: Transport, Schools, and Amenities
On an island of just 0.6 square kilometres with a single road causeway at Daleys Point, practical differences between the two streets are measured in seconds. Neither street has a public transport stop within 1,500 metres. Both are car-dependent. Woy Woy train station is about a 10-minute drive, Ettalong Wharf ferry to Palm Beach takes 35 minutes, and Sydney is roughly an hour and 20 minutes by car via the M1.
School catchments are identical. Empire Bay Public School is about a 16-minute walk and Brisbane Water Secondary College Umina Campus is roughly a 10-minute drive. Nearby private options include St John the Baptist Catholic Primary in Woy Woy South (about 11 minutes’ drive), Coast Christian School in Bensville (about 12 minutes), and Green Point Christian College K-12 in Green Point (about 12 to 13 minutes).
No shops or schools sit on the island. Ettalong Beach, Umina, and Woy Woy are all about five minutes’ drive for everyday amenities. Any driving-time difference between the two streets is negligible.
Conclusion
Cuttlefish Parade and Mainsail Avenue both deliver the core St Huberts Island waterfront lifestyle. Which suits you depends less on “better” and more on what you want from the experience. Cuttlefish Parade is the premium, move-in-ready, tightly held choice with a dress-circle feel. Mainsail Avenue offers a more accessible price point, architectural variety, and genuine renovation upside. Both streets have rewarded their owners, and both sit in one of the Central Coast’s most quietly desirable pockets.
