This stunning site offers huge boulders, creating canyons and shelves which stretch well out into the Strait. Strong currents are usually found here, demanding planning for slack tide, but the bigger schooling fish – jacks, rainbow runners, trevally and mackerel – large seafans in a variety of hues, encrusting invertebrates and various critters such as sea moths, devilfish and the current-loving Nembrotha purpureolineolata nudibranch make this a memorable dive. "Tanjung" means cape and "Tebal" means wide or thick, so this dive site is named for the thick part of the cape on which it lies, as seen from above.
