CBH Group is an integrated grain storage, handling and marketing co-operative controlled by growers for their benefit and the benefit of the grain industry in WA. It is owned and controlled by around 4,200 grain growers. The CBH Group was founded during the Great Depression through the realisation that a cheap and efficient bulk handling system would reduce growers' costs and strengthen the struggling wheat industry. The CBH Group was founded on 5 April 1933 with the trustees of the Wheat Pool of WA and Wesfarmers jointly registering the co-operative. It has grown to become Australia's biggest grain handler and also owns a 50 per cent stake in Interflour which operates seven flour mills in Indonesia, Vietnam, Malaysia and Turkey, including a grain port terminal in Vietnam.
