The ethnonym Gugigin has been related to a Yugambeh word, Gugin, which refers the north with -gin meaning "people" and thus means "Northern People". They were the northernmost clan of the Yugambeh.
Language
The Gugigin people spoke a dialect of the Yugambeh language.[1]
Country
Their tribal boundaries are said to have extended west to Oxley creek, south to Jimboomba and the Pimpama river, north to Mt Cotton and east to Russell Island and surrounds.
According to John Allen's map, the Gugigin were the northernmost clan, located north of the Mununjali clan on the Logan River, the Wangerriburra in Albert Valley.[2]
