Site details

The Numidia was a roughly 130 m British cargo steamer that struck the northern point of Big Brother Island in 1901 while bound for India. The wreck cascades down a steep drop-off from about 8 m at the bow to beyond 80 m, smothered in hard and soft corals. It is one of the two iconic Big Brother wrecks and a magnet for schooling fish and passing pelagics on the current-swept reef.
