Southwest Pacific: eastern Australia from Moreton Bay, Queensland to Eden, New South Wales, including Lord Howe and Norfolk Islands.
Found in sheltered bays, clear coastal waters and sometimes in estuaries (Ref. 27012). Generally herbivorous. Feed mainly on seagrasses and algal filaments (Ref. 26551, 27013). Eastern sea garfish also consume a high proportion of crustaceans (Ref. 27013). A schooling fish, found generally near the surface at night and close to the sea floor over seagrass beds during the day (Ref. 6390). They are being preyed upon by mulloway (Argyrosomus hololepidotus) and tailor (Pomatomus saltatrix), as well as coastal water birds. No studies have been reported on the spawning of this species (Ref. 6390).
