Seven genera and eleven species of lysianassid amphipods are recorded from the Great Barrier Reef, Queensland, Australia. Six species are new to science. Six of the eleven species are considered to be scavengers. The Great Barrier Reef lysianassid fauna is more similar to that of the tropical Indo-West Pacific than to that of temperate Australia.
