CBH Group
CBH Group is a farmer-owned Western Australian cooperative that receives, stores, transports, processes and markets cereal grain.
Last updated August 26, 2026
Overview
CBH Group, commonly known as CBH, is a farmer-owned cooperative and one of the central organisations in Western Australia's grain industry. Its name derives from Co-operative Bulk Handling, reflecting the business's original purpose: developing and operating bulk systems for receiving and moving grain produced across the state's Wheatbelt. CBH operates the great majority of cereal-grain receival facilities in Western Australia and connects farms with storage sites, rail and road logistics, port terminals, processors and overseas customers. The organisation was established on 5 April 1933 after more than two decades of unsuccessful proposals for bulk grain handling in Western Australia. Its formation occurred while a royal commission was examining the subject. The trustees of the Wheat Board of Western Australia and Wesfarmers registered the company with capital of £100,000, divided equally into 100,000 shares. From the beginning, the cooperative used a one-member, one-vote principle rather than allocating control according to the volume of grain supplied. That governance model remains central to CBH's identity as an organisation owned by growers rather than public shareholders. CBH's operating system covers multiple stages of the grain supply chain. Grain is delivered to receival points located throughout farming districts, where it is assessed, handled and placed into storage. From there, CBH coordinates movement to export terminals and other destinations through road and rail networks. The organisation also manages grain marketing and has activities connected with processing and value-added agricultural products. Its principal commodities include wheat and other cereal grains, with the mix varying by harvest and growing region. The cooperative's network historically relied heavily on Western Australian Government Railways branch lines and sidings. As some rail infrastructure aged and road transport expanded, CBH changed its logistics model. In 2009 it began putting rail grain haulage services out to tender, while retaining ownership of locomotives and wagons and contracting day-to-day operations to specialist rail companies. Watco Australia began operating services under a ten-year arrangement in the early 2010s, and Aurizon later assumed the operating contract. Rail services connect inland collection points with CBH facilities and export terminals at Albany, Geraldton, Esperance and Kwinana. CBH expanded its scale through the 2002 merger with Grain Pool, enabled by legislation passed by the Parliament of Western Australia. Grain volumes have fluctuated with seasonal conditions, but the cooperative has recorded several major intake and shipping records. Its network received 12.2 million tonnes in the 1999-2000 season, 14.7 million tonnes in 2003-04 and 15.8 million tonnes by January of the 2013-14 season. In 2016-17, receipts reached 16.6 million tonnes, accompanied by notable monthly rail movement and shipping records. CBH's economic role extends beyond grain handling. Its facilities and logistics activities support farming communities, transport operators, regional employment and Western Australia's export infrastructure. At the same time, the organisation has faced scrutiny over access to rail infrastructure and taxation. In 2013 it referred a dispute with the network owner then known as Brookfield Rail to the Economic Regulation Authority over access prices and network condition. In 2016, Australian Taxation Office data reported that CBH had generated more than $3.4 billion in revenue in 2013-14 while paying no tax, making it the country's largest revenue earner in that data set without a tax payment. CBH remains an active cooperative focused on grain supply-chain infrastructure, grower services and domestic and international marketing.
History
CBH Group was created on 5 April 1933 during a period of sustained debate about how Western Australia should handle and transport bulk grain. More than twenty years of proposals had failed to produce a comprehensive system, while a royal commission was examining the issue. The trustees of the Wheat Board of Western Australia and Wesfarmers registered the new organisation with capital of £100,000 divided into 100,000 shares. Its cooperative constitution gave each member one vote, regardless of the quantity of grain supplied, establishing a grower-oriented governance structure. CBH developed a network of receival points across the Wheatbelt, historically placing many facilities beside railway sidings and branch lines operated by the Western Australian Government Railways. These sites allowed grain to be aggregated in bulk and moved efficiently toward storage and export terminals. Over time, the number of receival points fell from a historical high of about 300 to fewer than 200, and the system became organised into Albany, Esperance, Geraldton and Kwinana zones, each divided into smaller operating areas. The cooperative grew alongside Western Australia's grain production. It received 12.2 million tonnes in the 1999-2000 season and 14.7 million tonnes in 2003-04. CBH merged with Grain Pool in November 2002 after Western Australian legislation authorised the combination. The merger strengthened the organisation's role in grain handling and marketing and consolidated important parts of the state's grain supply chain. Rail logistics became a major strategic issue as some branch lines and railway facilities deteriorated and road haulage gained importance. In 2009, CBH decided to tender its rail-grain operations, with an objective of increasing the share of grain moved by rail from approximately half to about 70 percent. Rather than outsource ownership of the fleet, CBH adopted a model in which it purchased locomotives and wagons and contracted specialist operators to plan and run services. In December 2010, Watco Australia won a ten-year operating contract for southern Western Australia. CBH bought 22 locomotives and 574 grain wagons for the arrangement. Watco was responsible for planning, scheduling, tracking, maintenance coordination, inventory control and crew management, while CBH retained ownership of the rolling stock. The first Watco service ran on 30 March 2012, ahead of the contract's formal commencement on 1 May. Delays in rolling-stock delivery meant that QR National continued some narrow-gauge services until October 2012, while locomotives were temporarily hired for standard-gauge work. Three additional locomotives were delivered in 2015 as compensation for delays. CBH connected inland receival facilities with terminal and port locations at Albany, Geraldton, Esperance and Kwinana over the open-access network managed by Arc Infrastructure. In 2013, CBH referred a dispute with Brookfield Rail concerning track-access prices and the condition of the rail network to the Economic Regulation Authority. The cooperative later expanded its locomotive resources by buying ten DB-class locomotives from Aurizon in 2017. When the rail contract was next tendered, Aurizon won a six-year agreement with an option for extension. Aurizon added wagon sets to the ten sets owned by CBH and began operating the services in September 2021, several months earlier than the planned May 2022 handover. Production growth produced further records. CBH handled 15.8 million tonnes by January of the 2013-14 season, and receipts reached 16.6 million tonnes in 2016-17. That latter season also produced records for December rail movements to port and January shipping volumes. The scale of the harvest was associated with an estimated contribution of more than $5 billion to the Western Australian economy. CBH has also attracted public scrutiny. In 2016, Australian Taxation Office data indicated that the cooperative had generated more than $3.4 billion in 2013-14 revenue while paying no tax. The disclosure made CBH Australia's largest revenue earner in the relevant data set with no tax payment. Despite such scrutiny and continuing infrastructure challenges, CBH remains an active farmer-owned organisation whose core activities span receival, storage, transport, processing and marketing of grain.
