The Ngamba language is poorly described because little has been transmitted of its nature. It is generally believed to have been similar to Gumbaynggirr.[1]
Ngamba territory comprised some 900 square miles (2,300 km2) from Port Macquarie and the vicinity of Rollands Plains south to the Manning River. The inland extension has not been ascertained.[2]
A few remnants of the original tribe were attested as still living in 1929, when A.R. Radcliffe-Brown described them as lingering on with descendants of the Ngaku and Daingatti.[3] According to the reminiscences of Harry Buchanan, they had been systematically and savagely exterminated by the Australian native police.[4]
The Ngamba exploited the mangrove species Avicennia marina for its bark in order to fashion their military shields.[5]
