Conditions & Currents

Conditions at Canons are generally favorable, with small, gentle waves and moderate wind, making for good diveability. Although there may be a sizeable offshore swell, the site itself is well-protected. The average water temperature of 28°C means a 3mm wetsuit is usually sufficient. Tide movements are present, with high tides reaching approximately 0.9m and low tides at 0.4m, but the site's protected nature mitigates extreme current impacts. Visibility typically averages 25 meters, allowing for clear views of the historical artifacts and marine life. This site is suitable for various diver levels due to its calm and shallow nature, but awareness of general conditions is always recommended.

Dive profile & how the dive runs

Diving at Canons typically begins with a boat entry, often following a leisurely lunch on Direction Island. The site's shallow depth, ranging from 8 to 12 meters, allows for an easy exploration. Divers navigate across the seabed, observing the two distinct clusters of six iron cannons and the surrounding historical debris field, which includes metallic wreckage and old telegraph cables. The dive is usually conducted as a multi-level profile, allowing ample time to explore the historical artifacts and the abundant natural reef life, including frequent sightings of the resident dugong 'Kat', dolphins, and manta rays. The shallow depth naturally facilitates extended bottom times and a safe ascent directly from the site without specific turn points, concluding with a standard safety stop at 5 meters. This relaxed profile makes Canons suitable for divers of all experience levels.

Underwater photography

Canons, with its clear, warm waters and shallow depths, offers excellent wide-angle photography opportunities for capturing the historical cannons alongside marine life. A wide-angle lens is ideal for showcasing the scale of the artifacts and schooling fish. For close-up shots of gobies or nudibranchs, a macro lens can also be effective. Natural light is often sufficient due to the shallow profile and good visibility, but strobes can enhance color and detail, particularly for the rusted iron. Buoyancy control is paramount to avoid disturbing the historical site or the sandy bottom, especially when seeking out smaller creatures. Be mindful of marine life, giving ample space to the resident dugong and mantas.

Getting there & logistics

Accessing the Cocos (Keeling) Islands, Australia's most remote dive destination, requires flights to Christmas Island, typically from Perth, followed by onward travel. The diving itself is primarily operated by Cocos Dive, the sole dive operator on the islands, based out of West Island. Due to its remote location, liveaboard options are less common for local dives, with most excursions being day trips by boat to sites like Canons, which are just a short ride from shore. Booking dives well in advance is highly recommended due to limited availability and seasonal tour operations. There are no specific park fees mentioned for individual dive sites, but travel to the remote territory involves standard flight and accommodation costs.

Safety & environment

The nearest recompression chamber facilities are not readily available on the Cocos (Keeling) Islands due to their extreme remoteness. In the event of a dive emergency requiring recompression, evacuation to mainland Australia (Perth) or a facility in a neighboring country would be necessary, a process that can be time-consuming and logistically complex. Therefore, comprehensive dive insurance with emergency evacuation coverage is essential for all divers. Site-specific hazards at Canons are minimal due to its shallow, protected nature, but standard safe diving practices, including monitoring air consumption and no-decompression limits, are always crucial. Divers should stay hydrated, follow guide instructions, and avoid touching or disturbing the historical artifacts and marine life.
