1. Territorial Boundaries & Coastal Granitic Headlands

The Njunga Sovereign Subnation (Nyunga, W13 in AIATSIS classification) held customary sovereign authority over the dramatic turquoise bays, white quartz sand dunes, and granite headlands of the south-eastern coast.^[1] The sovereign territory extends from the Young River in the west, through Esperance Bay (Kepa Kurl) and Cape Le Grand (Mandoowernup), eastward past Cape Arid to Israelite Bay, where it forms the eastern marine gateway of the Bibbullmun Sovereign Nation.^[1][2]

Custodial authority encompassed not only the mainland littoral plain and coastal lakes (Lake Gore, Pink Lake), but also customary jurisdiction over the hundreds of granite islands and islets of the Recherche Archipelago.^[2][3] Regional hearth estates (kalla-boodja) included:
Kepa Kurl (Esperance): The central sheltered bay estate where fresh water seeps through coastal dunes into the sea (Kepa Kurl, meaning 'where the water lies like a boomerang').^[3][4]
Mandoowernup (Cape Le Grand): The massive granitic headlands and sheltered beaches where seasonal mullet and salmon schools congregated.^[4][5]
Cape Arid & Israelite Bay: The remote eastern maritime frontier managing complex littoral lagoons and coastal mallee scrublands.^[5][6]

2. Archipelago Navigation & Maritime Resource Governance

Njunga custodians developed a rich maritime littoral culture adapted to the offshore island chains of the Recherche Archipelago.^[7] In pre-colonial deep time, when sea levels were lower during glacial periods, the islands were connected to the mainland as high granitic hills, hosting extensive occupation sites and chert tool manufacturing.^[7][8]

Following post-glacial sea level stabilization approximately 6,500 years BP, Njunga custodians maintained seasonal access to inshore islands during calm summer conditions (Bunuru), harvesting fur seals (Arctocephalus forsteri), muttonbirds (Ardenna tenuirostris), and penguin eggs.^[8][9] Coastal fish weirs constructed of granite cobbles were erected across tidal estuaries to trap migratory Australian salmon, whiting, and bream without exhausting breeding populations.^[9][10]

3. Coastal Hydrology & Sand Dune Micro-Aquifers

The freshwater ecology of the Njunga domain was governed by delicate coastal sandplain aquifers and perched freshwater soaks.^[11] Along the vast dunefields of Esperance Bay, custodians located potable water by excavating shallow sand wells (Kepa) directly behind primary foredunes, tapping into freshwater lenses that floated above denser saltwater layers.^[11][12]

On the inland sandplains, women gathered the edible bulbs of native orchids, yams, and kangaroo apples (Solanum laciniatum), while processing the nectar of coast banksia (Banksia speciosa) into rich sweet infusions.^[12][13] Meticulous cool burning of coastal acacia scrub was executed in autumn to regenerate succulent grazing lawns that drew western grey kangaroos down to the shoreline.^[13][14]

4. Frontier Sealing Invasions, Pastoral Seizures & Enduring Title

In the early nineteenth century, long before official British settlement, American, French, and colonial sealers and whalers raided Njunga waters, operating lawless outposts in the Recherche Archipelago.^[15] Archival logs and oral histories document that sealers frequently kidnapped Njunga women and violently dispossessed mainland coastal camps.^[15][16]

Official pastoral expansion began in the 1860s when the Dempster brothers established grazing leases at Esperance, violently alienating waterholes and displacing traditional foraging grounds.^[16][17] Despite frontier violence, epidemic disease, and twentieth-century assimilation policies, Njunga families maintained an unbroken genealogical and custodial presence across their ancestral beaches and headlands.^[17][18] Under the doctrine established in Mabo [No 2]* and international human rights conventions, Njunga sovereignty over their ancestral waters and granite coasts remains absolute, enduring, and unceded.^[18][19]
