For over 100 years, Big River Group has been manufacturing and distributing quality building products from our Australian facilities. From formwork and plywood to engineered flooring and lightweight walling — we back builders at every stage.
Founded in the 1920s in Grafton, New South Wales, Big River Group started as a regional sawmill serving the local building industry. Over the decades, we grew from a single timber operation into a national building products manufacturer and distributor.
Today, we still operate the original Grafton mill — combining generations of Australian hardwood expertise with modern manufacturing capability to deliver products trusted by builders across the country.
