Remote Miri-Sibuti drop-off with reef-to-wall structure.
Tukau Drop-off is a remote Sarawak offshore reef in the Miri-Sibuti Coral Reefs National Park, reached by a long boat run and shaped like a reef that falls quickly into a wall. The site is known for big-fish encounters, schooling life and clear-water windows, while the real planning work is the offshore logistics, gas management and keeping the profile tidy on the drop-off.

Scuba Diving
A boat-only drop-off with a reef top and wall, so keep trim tight and work the structure slowly.

Snorkeling
Not a snorkel site; the main action is below the surface on the reef edge and wall.
