Established in January 1922 at Koonwarra, the Leongatha Brickworks was short lived, lasting for only 5 years. This appears to have been the second brickworks in Leongatha, as Mewburn' brickworks was operating from about 1890.
The Yallourn Brickworks was established by the State Electricity Commission in 1921 to produce bricks for the construction of the Yallourn power station and associated Yallorne town. W H (Dad) Brewer managed the Yallourn brickworks for the SEC. When demand decreased he leased the brickworks up to the late 1940's changing the "YALLOURN" stamp to "BREWER".
