How did Eddie mabo start his case?

Eddie Mabo began his landmark case in 1982 when he and four other plaintiffs filed a claim in the High Court of Australia, seeking legal recognition of their traditional land rights on Mer Island in the Torres Strait. This action was a response to the Australian government's denial of their connection to the land, which had been denied under the doctrine of terra nullius, asserting that Australia was uninhabited before European settlement. Mabo's case challenged these legal precedents, ultimately leading to a historic ruling in 1992 that recognized native title in Australia.
