The runway tilts uphill. That's the first thing pilots notice about Wau, and the thing that every aviator who ever flew into the Wau-Bulolo Valley in the 1930s and 1940s had to learn quickly: you commit to the landing because you cannot go around. Wau sits at roughly 1,100 meters in a bowl ringed by the Owen Stanley Range, and the airstrip was carved by gold miners who could not be bothered to find flat ground. That gamble shaped everything. Gold drew the miners. The miners built the strip. The strip, a quarter century later, carried Australian artillery into a fight that stopped an entire Japanese offensive cold. Today Wau is a quieter place, a market town in Morobe Province where the gold has mostly played out but never quite vanished.
The 1920s and 1930s gold rush that built Wau was not a quick boom. Prospectors who came inland from Salamaua on the coast, along the brutal Black Cat Track, found enough color in the creeks of the Wau-Bulolo Valley to justify permanent investment. Together with nearby Bulolo, Wau became a proper mining center: houses, workshops, electricity, a water supply, and the critical aerodromes that linked the high valley to the outside world. Most of the easy gold has long since been taken, but the hunger never entirely left. Industrial operations continue at two sites in the area, and on any given morning locals still pan the Bulolo River and its tributaries, working the same gravel their grandfathers worked.
The same airstrip that made Wau viable also made it a military target. In January 1943, Japanese forces tried to seize it in what became known as the Battle of Wau. A small Australian garrison, frantically reinforced by Dakotas that had to thread storm passes over the Owen Stanley Range, held the strip against an attack that reached the corner of the airfield itself. The Japanese were thrown back. Today remnants of that fighting lie scattered through the surrounding country. Plane wrecks rust on ridges. Bomb craters pit the jungle. Live munitions still surface in the ground. The war did not end cleanly here; it simply stopped and was absorbed into the forest.
Two trails define Wau as much as the gold or the airstrip. The Black Cat Track runs four to five days north from Wau to Salamaua on the coast, through some of the bloodiest ground of the Pacific war. The trek, when it was still regularly guided, meant eight or nine hours a day of hard walking, sleeping in local villages, and ending with a raft trip down the Francisco River to the sea. The Bulldog Trail runs south-southwest, the supply line along which Australian troops and Papua New Guinean carriers moved food and ammunition from Port Moresby during the battle for Wau. Both are punishing. As of 2017 neither was routinely guided; the old trekking infrastructure has largely lapsed, and only solo travelers or small parties, hiring village guides directly and accepting real risk, still move along them.
Wau connects to Lae, Papua New Guinea's second-largest city, by road. Public Motor Vehicles, the shared minibuses known locally as PMVs, load in downtown Lae and run up to Wau and Bulolo, making the trip in about five hours with multiple stops. Return runs leave Wau early in the morning and collect passengers in Lae in the afternoon. Flying has become rarer than it once was. A single weekly flight from Lae on a North Coast Aviation Islander was the only scheduled air service as of 2017, with no direct connection to Port Moresby. The Wau Ecology Institute, once famous for its museum and its astonishing stick insect collection, burned down a few years before that, and had not returned. Accommodation is thin: there is the aging Wau Motel, local markets, two general stores, and the rhythms of a town that has adjusted to being smaller than it used to be.
Wau is, today, a town that carries a heavier history than its size suggests. A century ago it was the end of one of the roughest walks in the Pacific. Eighty years ago it was the airstrip on which a small Australian brigade stood off an army. Now it is a market town in the highlands of Morobe, surrounded by steep ridges, butterfly-haunted forest, and creeks where a sharp eye and a tin pan can still find a flake or two of the metal that started it all. The Francisco River still runs down to Salamaua. The Owen Stanley clouds still pile up each afternoon. The runway still tilts uphill.
Located at 7.34 degrees South, 146.72 degrees East, at approximately 1,100 meters elevation in the Wau-Bulolo Valley of Morobe Province. The airstrip (ICAO AYWU) is notorious for its pronounced uphill slope, which historically required high-speed committed approaches because go-arounds were impractical. The surrounding Owen Stanley terrain generates frequent afternoon storms, vertical drafts, and valley mists; mornings offer the most reliable VFR window. Nearest major airfield is Lae Nadzab (AYNZ), roughly 50 nautical miles northeast. From cruising altitude, look for the cleared terraces of the valley floor cut into otherwise dense jungle ridgelines, with the modest town clustered around the sloped strip.
