Little is known of the details of the Marrago domain, which was in western Queensland, but Norman Tindale calculated, by default, that their tribal lands covered roughly 1,300 square miles (3,400 km2) around the area of the Alexandra River.
Gavan Breen (1981) thought that they might have been a sub-group of the Mayi Kutuna people; Paul Memmott (1994) lists their language but gives no further detail. Their status is unconfirmed by the AIATSIS collection.[1]
