[2] Norman Tindale estimated the extent of Maung territory at 500 square miles (1,300 km2), covering both the Goulburn Islands and the adjacent coastal lands.
The harbinger for the end of the wet season was the peewee, whose arrival signaled that it was time to harvest mawain, a type of water lily root.
[5] Brown scum, mangirgirra, on the coastal waters meant it was time to go out and fish for a small variety of shark, which abounded at this time, in August; when the waluru' or stringy bark began to flower, it meant that turtles were mating, and, once the blossoms were due to fall, the hunting period for these turtles began.
The technique which was introduced however was one derived from observation of the coiling method current among the weavers of the Ngarrindjeri tribe which the Methodist instructor, Gretta Matthews, had learnt of while in Glenelg, South Australia.
The mastery of this technique had a major impact as Iwadja relatives on Croker Island, the Kunibidji in the Maningrida area and the Kunwinjku at Gunbalanya (Oenpelli) learnt it, and in turn it was spread throughout Arnhem Land and the Gulf of Carpentaria.
