The islands were created through a massive engineering project involving land reclamation and dredging of the Broadwater. It was designed specifically to cater to the burgeoning luxury market of the late 20th century, offering bridge-free ocean access.
Today it is a strictly residential, high-security enclave characterized by palatial multi-storey mansions and private superyacht berths.
- Unrivalled privacy and security within a gated environment
- Direct, bridge-free access to the Pacific Ocean for large yachts
- High architectural standards with strictly enforced building covenants
- Quiet residential atmosphere with no through-traffic
- Proximity to the dining and boutique retail of Paradise Point
- High annual body corporate or precinct levies for security and maintenance
- Vulnerability to storm surges and projected sea-level rises
- Substantial maintenance costs for canal walls and pontoon systems
- Limited public transport and high reliance on private vehicles
- High entry price point limits the secondary market liquidity

Residents value the absolute privacy and the ability to moor large vessels at their back door. There is a strong sense of security, though some note the lack of 'village' feel on the islands themselves.
The peace of mind knowing the gate is manned 24/7 is why we stay.
No bridges to worry about means I can have a much larger yacht than in other canal estates.
The land tax and levies are eye-watering; you need deep pockets to hold property here.
It's a beautiful place for the kids to grow up, but we spend a lot of time driving them to school and sports.
The covenants ensure quality, but they can be quite restrictive when you want to innovate.
The quietest place on the Gold Coast. No hoons, no noise, just the water.
