Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.

Samarai was once a thriving colonial port, and its long wharf has spent the decades since converting harbor junk into habitat. Pilings wear sponges and soft corals like upholstery; the rubble below hides mandarinfish that rise to court at dusk, frogfish wedged among bottles and cable, ribbon eels, and squadrons of striped catfish sweeping the silt. Batfish circle the structure in loose formation. The China Strait's tide keeps everything fed and demands the schedule be respected. It is a classic pier dive — history overhead, oddities below — and dusk here, waiting on the mandarinfish, is a Milne Bay ritual.

The moment you come for: Mandarinfish courtship at dusk; piling growth and glassfish; a working museum of port-town debris turned reef.

Topography: Wharf pilings, sunken debris, and silty rubble from a century of harbor life

Current: The China Strait funnels tide past the island; dives run at slack or on the gentle phase.

Entry: Dived beside the old island wharf in the China Strait; timed around the strait's tides.

Know before you splash

Hazards: Tidal current in the strait; sharp metal and glass in the rubble; low visibility on the wrong tide.

Conservation: The wharf is village front yard as much as dive site — courtesy ashore, no artifact collecting below.
