Australia's Building Products Partner Since 1920
From our origins as a Grafton timber mill to a national manufacturer and distributor, Big River Group has been supplying Australia's builders for over 100 years. We combine deep product expertise with a network of 15+ locations to deliver the materials and support your projects need.
From Grafton Timber Mill to National Partner
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.

Our Armour brand range – ArmourForm, ArmourFloor, ArmourCab, and ArmourDeck – is engineered and manufactured right here in Australia. Every product is designed for Australian conditions, tested to Australian Standards, and backed by local technical support.
