Cable Bommie
Reef-and-relic boat dive with coral life and a current-prone ridge.
Local operator required
Public destination guidance and operator coverage both indicate routine access is by local guided boat trip rather than shore entry.
About Cable Bommie
Cable Bommie is a boat-access reef site near Home Island where old cable gear and winches lie beside coral growth, reef fish, and the bommie that gives the dive its name. The route mixes underwater relics with living reef structure, so the site feels as much like a coral dive as a piece of local maritime history. Most of the dive is spent around the bommie and surrounding reef before attention shifts toward the nearby ridge, where water movement can increase and larger animals are more likely to appear. Lionfish are regularly associated with the bommie, while grey reef sharks and manta rays are the better-known visitors when the outer edge is active.

Key Hazards
Safety Notes
The main bommie area is comparatively straightforward, but the ridge deserves tighter buddy control and current awareness when the dive extends into more open water.
Access Restrictions
Cable Bommie is typically dived through the islands' local operator rather than as an independent entry, and access depends on boat scheduling and daily sea conditions.
Legal Notes
The site lies within the Cocos (Keeling) Islands Marine Park, so local marine-park rules and operator guidance apply.
