Blackall Woolscour, Heritage industrial complex in Blackall, Australia.

Blackall Woolscour is a complex of timber-framed, corrugated-iron sheds 4 kilometres northeast of Blackall, Queensland, built in 1908 for the Blackall Proprietary Woolscouring Company. Its L-shaped main building sequences shearing, classing, scouring, drying and pressing spaces, with a long skylit shed housing the steam-driven scouring machinery and a small office in its southwestern corner.

The facility opened in 1908 and operated for more than 70 years as a large-scale wool cleaning station. Its closure in 1978 marked the end of an important chapter in Australian wool production.

The name comes from the process itself: wool scouring, which replaced sheep washing in Australia by the 1890s. The shearing board is still in use, and the site is now the only fully working historical steam-powered woolscour museum in the world. The Blackall Proprietary Woolscour Company was chaired by John Henry Hart.

The site is easy to walk around and clearly laid out, with open areas to explore between the buildings. Wear comfortable shoes since the ground is uneven and some sheds have steps to enter.

The complex preserves machinery that has changed little since it was installed, showing an almost complete production line from the early 1900s. Few places anywhere display such well-kept original steam-powered equipment still intact.
