Herbert & Burdekin Region

The Herbert and Burdekin Region encompasses two of Queensland's most important sugar-producing districts: the high-rainfall Herbert River district surrounding Ingham and the extensively irrigated Burdekin district centred on Ayr and Home Hill.

The region contains six operating sugar mills, all operated by Wilmar Sugar Australia, together with the bulk sugar export terminals at Lucinda and Townsville. The two districts have contrasting agricultural environments but both support large-scale milling operations and extensive cane railway networks. The Herbert district contains Macknade and Victoria, while the Burdekin contains Invicta, Pioneer, Kalamia and Inkerman.

The area's sugar industry developed from nineteenth-century plantation enterprises into an industry supplied predominantly by independent cane growers. During the twentieth century the mills underwent repeated expansion and consolidation, with all six eventually becoming part of the Wilmar group. Raw sugar from the Herbert mills is exported through Lucinda, while production from the four Burdekin mills is transported by heavy rail to Townsville.

Lucinda Bulk Sugar Terminal

The Lucinda Bulk Sugar Terminal opened in 1958 and is the export terminal for raw sugar produced by Victoria Mill and Macknade Mill. Raw sugar is transported from both factories to Lucinda over the Herbert district's 610 mm (2 ft) gauge railway.

The original bulk terminal used an inshore berth, but increasing vessel size and the limitations of the shallow Hinchinbrook Channel led to construction of the present offshore loading facility between 1975 and 1979. Its 5.76-kilometre jetty carries an enclosed conveyor to a deep-water berth and shiploader and is one of the longest structures of its type in the world.

The terminal is owned and operated by Sugar Terminals Limited and has three storage sheds with a combined capacity of approximately 235,000 tonnes.

Macknade Mill

Macknade Mill commenced crushing in 1873 on the banks of the Herbert River and is the oldest continuously operating sugar mill in Australia.

Established by Arthur and Frank Neame as a plantation enterprise, Macknade progressively developed into a central mill supplied by independent growers. CSR acquired the property in 1896 and operated it for more than a century before its sugar business passed to Wilmar in 2010.

Today Macknade processes an average of approximately 1.5 million tonnes of cane annually and is connected with neighbouring Victoria Mill by the Herbert district's integrated cane railway network.

Victoria Mill

CSR established Victoria Mill in 1883 approximately 3 kilometres east of Ingham. The factory developed from a large plantation mill into one of Australia's highest-throughput sugar factories.

Victoria is a dual-milling-train factory and processes an average of approximately 3 million tonnes of cane annually, producing about 400,000 tonnes of raw sugar. Wilmar describes Victoria as regularly vying with Invicta Mill for the position of Australia's largest sugar mill.

Victoria and Macknade share an interconnected 610 mm gauge cane railway system, and finished raw sugar from both factories is transported by rail to the Lucinda Bulk Sugar Terminal.

Townsville Bulk Sugar Terminal

The Townsville Bulk Sugar Terminal was completed in 1959 at the Port of Townsville. It is the principal export terminal for raw sugar produced in the Burdekin district.

Raw sugar from Invicta, Pioneer, Kalamia and Inkerman is transported to the terminal over the 1,067 mm (3 ft 6 in) heavy-rail network.

The terminal is owned and operated by Sugar Terminals Limited and contains three storage sheds with a combined capacity of 750,000 tonnes.

Invicta Mill

Invicta Mill commenced crushing at its present site at Giru in 1921. Its history can be traced through earlier Invicta milling operations in northern New South Wales and at South Kolan near Bundaberg before the plant was relocated to the Haughton River district.

Large-scale development of irrigated cane land following construction of the Burdekin Falls Dam led to a major expansion of the factory during the late twentieth century, including installation of a second milling train.

Invicta now processes an average of approximately 3 million tonnes of cane annually and produces around 440,000 tonnes of raw sugar, making it Australia's largest mill by raw sugar production.

Pioneer Mill

Pioneer Mill near Brandon commenced crushing in 1884. The Pioneer enterprise was established by a partnership associated with the Drysdale family and became particularly important in the development of irrigation in the Lower Burdekin.

The work of George and John Drysdale in developing groundwater irrigation helped demonstrate the viability of intensive sugar cultivation in a district with markedly lower and less reliable rainfall than the tropical coast.

Pioneer is unique among Queensland sugar mills in operating its cane railway principally to 1,067 mm (3 ft 6 in) gauge. It also contains a 68 MW cogeneration plant which Wilmar describes as Australia's largest biomass-only electricity generator.

Kalamia Mill

Charles and John Young established the Kalamia Estate in 1882, with Kalamia Mill commencing sugar production in 1884.

The property later passed to the Australian Estates and Mortgage Company, which operated Kalamia for much of the twentieth century. CSR acquired Australian Estates in 1975, bringing the mill into the CSR sugar group.

Kalamia is now the smallest of Wilmar's four Burdekin factories, processing an average of approximately 1.5 million tonnes of cane and producing about 230,000 tonnes of raw sugar annually.

Its 610 mm gauge cane railway connects with neighbouring mill systems through sections of dual-gauge track associated with the 1,067 mm gauge Pioneer Mill network.

Inkerman Mill

Inkerman Mill at Home Hill was established by John Drysdale and commenced crushing in 1914. The development of the factory was closely associated with the expansion of irrigated settlement south of the Burdekin River.

The dual-milling-train factory processes an average of approximately 1.7 million tonnes of cane annually and is one of only two Australian sugar mills, together with Invicta, to use a cane diffuser.

Inkerman is the only operating Burdekin mill situated south of the river. Its modern 610 mm gauge cane railway is physically isolated from the interconnected Invicta, Pioneer and Kalamia systems on the northern side, with no permanent cane railway crossing of the Burdekin River.
