Wau History. Wau is situated at an altitude of around 1100 metres in Morobe Province PNG. The Wau Ecology Institute is a biological research station situated near Wau. Wau was the site of a gold rush during the 1920s and 30s. While much of the mineral reserves have been extracted, industrial gold mining continues at Edie Creek and at the newly established Hidden Valley Gold Mine operated by Harmony Gold - South Africa.
