Monotaxis grandoculis has a wide Indo-Pacific distribution, from the Red Sea and the coast of eastern Africa to as far south as South Africa, across the Indian Ocean, although it is absent from the Persian Gulf. In the Pacific Ocean it extends as far east as the Hawaiian Islands, north to southern Japan and south to Australia. In Australia it is found at Christmas Island and the Cocos (Keeling) Islands and from Ningaloo Reef, Rowley Shoals and Scott Reef off Western Australia north to northeast of Evans Shoal in the Timor Sea and from the northern Great Barrier Reef south to Seal Rocks, New South Wales, with juveniles reaching as far south as Sydney. This fish lives close to reefs in sand and rubble areas at depths between 3 and 150 m (9.8 and 492.1 ft).

Monotaxis grandoculis is a target for commercial and artisanal fisheries wherever it occurs, as well as being taken by recreational anglers. Techniques used to take these fishes include gill netting, fish traps, spearfishing and handlining. The catch is marketed fresh. In the Marshall Islands the consumption of this species has been thought to be a cause of ciguatera poisoning.
