What is "mabuiag"

The Mabuiag or the Mabuygilgal are an Indigenous Australian group of Melanesian Torres Strait Islander people that are united by a common language, strong ties of kinship and survived as skilled hunter–fisher–gatherers in family groups or clans living on a number of Torres Strait Islands including Mabuiag Island, in the Torres Strait in Queensland, Australia.

They in common with all Torres Strait Islanders had a mixed reputation for hostility as well as eagerness to develop trading links with outsiders before they became Christian in the early 1870s. The language of the island is the Gœmulgau (Mabuylgau) Ya sub-dialect of Kala Lagaw Ya.

The society consists of two moieties ("koey buway"), the Gumuligal of Wagedagam ('Rear-Side') on the northwest (kukidagam) side of Mabuiag (their totem wind and direction), and the Mabuygilgal people of the Paipaidagam ('Near-Side') on the south-east side (sagerdagam), their main totem wind and direction. Sub-buway are those whose wind/direction is the southwest (zeydagam), and those whose totem wind/direction is the north-east (naygaydagam).
