Here the land and the sea are not two things but one. That principle runs through the Laynhapuy Indigenous Protected Area, a vast sweep of Yolngu Country in north-east Arnhem Land where the responsibility to care for place is as old as the place itself. Stretching from the Gove Peninsula south to Blue Mud Bay, this is homelands country - scattered communities where families live on their own clan estates, the way Yolngu have always sought to. The IPA simply gives a modern, formal name to an ancient duty, and puts its management exactly where it belongs: in Yolngu hands.
An Indigenous Protected Area is land and sea that First Nations people choose to manage for conservation and culture, through a voluntary agreement with the Australian Government, as part of the National Reserve System. Laynhapuy was dedicated in 2006, extended in 2018, and further expanded in 2025, and today it covers more than 1.2 million hectares of land and sea Country. Crucially, the agreement is voluntary - it does not hand control to Canberra. It recognises a partnership in which Yolngu set the terms for their own Country. Around 1,100 Yolngu people live within the area, across some thirty homelands administered by the Laynhapuy Homelands Aboriginal Corporation, based at Yirrkala. The arrangement reflects a hard-won principle of the homelands movement: that people thrive when they live on, and look after, the land their ancestors belonged to.
The work falls to the Yirralka Rangers, established in 2003. The name itself carries meaning - yirralka speaks to the bond and the obligations between Yolngu and their country. More than forty Yolngu rangers are employed across the homelands, organised into Dirramu (men's) and Miyalk (women's) groups so that knowledge and responsibility pass correctly through the right people. Their emblem is the Ganybu, the traditional triangular fishing net - a quiet statement that this is saltwater country as much as land. The rangers blend Yolngu knowledge with Western science, deciding together which species and which sites matter most and how best to protect them.
The numbers hint at the richness: the Laynhapuy IPA holds records of 48 listed threatened species and 52 listed migratory species, and it takes in internationally significant wetlands and coastal landforms. The rangers' management plan reaches across the whole estate - tending culturally significant sites, managing fire the way the country needs it rather than letting destructive late-season wildfires run, controlling introduced weeds and feral animals, and watching over the sea's most vulnerable travellers. Marine turtles haul out on these beaches to nest; dugongs graze the seagrass meadows offshore. Both are central to Yolngu life and law, and both are now monitored and protected by rangers who can read the country in ways no outside expert could. Fire management here is not only ecological housekeeping but increasingly a livelihood, generating carbon credits that help fund the work. It is conservation and cultural practice braided into the same daily act.
Laynhapuy is not a fenced-off park emptied of people. It is the opposite: a working homeland where families remain on their estates, where children grow up knowing the names of the headlands and the songs that belong to them, where caring for Country is a job, a duty, and an inheritance all at once. By keeping rangers employed on the land, the IPA also helps keep the homelands themselves viable - giving young people a reason and a means to stay on their clan estates rather than drift to distant towns. The rangers patrol coastlines that their ancestors patrolled, and the IPA gives that continuity a place in the national reserve system without ever pretending the land needed outsiders to make it valuable. It was always valuable. The achievement here is that Australian law has finally come around to saying so - on Yolngu terms, under Yolngu management, with both land and sea recognised as the single, inseparable Country the Yolngu always knew them to be.
The Laynhapuy IPA centres on roughly 12.43°S, 136.32°E in north-east Arnhem Land, sprawling along the coast from the Gove Peninsula south toward Blue Mud Bay and inland across the homelands. The natural gateway is Gove (Nhulunbuy) Airport (ICAO YPGV) on the Gove Peninsula, with numerous small homeland airstrips scattered through the area and Darwin International (ICAO YPDN) far to the west. From altitude the country reads as a mosaic of eucalypt savanna, monsoon forest, mangrove-fringed estuaries and an intricate coastline of bays, islands and seagrass shallows - the dugong and turtle habitat the rangers watch over. The tropical savanna climate brings a wet season from roughly November to April, with monsoon storms, building cumulus and reduced visibility, and a clear dry season well suited to coastal flying. All of this is permit country: entry to Arnhem Land and these homelands requires authorisation from the Northern Land Council, and visitors should respect that the area is actively managed by the Yirralka Rangers.
