A spectacular night dive location due to its sheltered position inside Wongat Island, several hundred meters from the bomber. Originally an iron sailing vessel, converted for action during WW1 and again in WW2 it was last used as the flag ship of Pimpco Shipping on coastal freight service along the coast of PNG. It once has the distinctions of being the oldest commercial vessel still in use in Pacific Waters and even when it was sunk, the iron hull had many more years serviceable life.
The 65 feet ship is now jam-packed with soft corals, sea fans and hydroids. At night the stark reds, pinks and oranges and silhouetted vividly against the pitch, night sea. The hold also contains the remains of a rusting dodge truck, and some very large cod. There are several small patches of the stinging yellow-brown milleprids, but these are greatly outnumbered by the delicately branched "Stylasterid" called the "Elegant Hydrocoralline". In the sheltered confined of the wreck, its brilliant pink clouration, contrasts beautifully with the deep reds of the "bryozoans".
Many species of "crinoid" can also be seen clinging to the rails and hatches of the wreck. At night their long feathery tentacles sway to and fro in the gentle current seeking to catch passing plankton.
