Pictures of Jim's Crack were recently published in Dan Groshong's coffee table book "Timor-Leste: Land of Discovery" (Tayo 2006) but the site is called K-57. If you dive there, look seaward immediately upon entry as many divers have been "buzzed" by a curious and large mackerel who usually comes around to see what all the noise is about. Those with spare air at the entry point on the western end of the wall can drift farther west on a gentle current and examine a shallow under hang at 4-5m which makes a nice decompression stop. Lionfish and bright small tropical fish are found there. The site has the usual cast of characters such as sharks, rays, turtles, barracuda with manta rays seen leaping in the bay and a giant Napoleon Wrasse sighted at the point. We also saw nudibranchs (various), and large coral fans.
