Slade Point is a hinge in the coastline. It marks the northern tip of Searcy Bay and the southern tip of Sceale Bay, a stubby promontory that shoulders the two apart. Stand here and the Great Australian Bight spreads out in front of you, all the way to Antarctica with nothing in between. The nearest town, Streaky Bay, sits about 29 kilometres to the north. Around the point, low cliffs and pale rock meet the relentless swell of the Southern Ocean, which arrives after a fetch of open water so vast it has been building since the far side of the planet.

When the point was finally named in 1908, it honoured a public servant rather than an explorer or a settler. The name commemorates William E. Slade, who had served as Assistant Engineer of Harbours in the South Australian government. It was the kind of quiet bureaucratic christening that filled in the blank spaces on colonial maps once the dramatic age of exploration had passed. No grand story, no shipwreck, no battle. Just a surveyor's tidy decision to fix a label to a headland that the great Flinders himself had let slip by unrecorded.

Flinders missed Slade Point, but he left his fingerprints all over the rest of this shoreline. Just days earlier, on 5 February 1802, he had anchored a little to the north and noticed the sea oddly discoloured, marbled with pale streaks. He duly wrote in his log that he called the place Streaky Bay, never knowing that the streaks are now thought to be oils released by certain species of seaweed below. That was how the western Eyre coast got its names, headland by headland, bay by bay, as the Investigator crept along charting a continent's hidden edge. Slade Point's silence on those charts is a reminder of how much depended on a single clear day, and how a passing haze could erase a piece of coastline from the record for a century.

In recent years this stretch of coast has been gathered into a web of conservation. Since 2012, Slade Point has bordered the Cape Blanche Conservation Park, and the waters lapping its base sit inside a habitat protection zone of the West Coast Bays Marine Park. The protections recognise what makes this coast precious: undisturbed shoreline, breeding habitat, and the rich marine life of the Bight, from sea lions and dolphins to the seabirds that work the swell. It is a landscape valued now less for what people might build on it and more for being left almost exactly as Flinders glimpsed it, or failed to, through the haze.

There is a particular feeling to standing on Eyre Peninsula's western shore. The land behind you flattens into low scrub and farmland, dry and wind-combed, and then the continent simply stops. Slade Point is one of countless unremarkable-looking headlands along this coast, yet each one is a small frontier, a place where Australia ends and the ocean takes over completely. The point has no town, no jetty, no monument. It is exactly the kind of place that rewards arriving quietly and watching the swell roll in from the bottom of the world.
