Alimatha Jetty

Alimatha Jetty is a shallow artificial-reef dive built around the resort jetty on Alimatha Island, where concrete pillars and coral-encrusted bommies create habitat that attracts abundant marine life. The site is noted for resident tawny nurse sharks that regularly gather on the sandy bottom and beneath the jetty posts; marble rays (stingrays) and schools of trevallies are also common, making the site a hotspot for underwater photography and close wildlife encounters. Depths range from about 1 m at the surface to around 15 m max, with typical dives at 5–10 m. Entry and exit are from the shore via the jetty ladders, so no boat is required. The sheltered lagoon usually offers good visibility (often 15–25 m) and warm water year-round (mid-20s°C). Currents are generally mild but occasional moderate flows can occur. Conditions are gentle and suitable for snorkelers and open-water divers, and night dives under the jetty lights are highly recommended for concentrated wildlife activity; divers should avoid touching or disturbing the animals.
