Inkerman Sugar Mill is a sugar mill located at Home Hill, Queensland, on the southern bank of the Burdekin River. Established by sugar industry pioneer John Drysdale, the mill commenced crushing in 1914.
Inkerman is one of four operating sugar mills in the Burdekin district and the only one situated south of the Burdekin River. It is operated by Wilmar Sugar Australia and is a dual-milling-train factory processing an average of approximately 1.7 million tonnes of sugarcane annually.[1]
History
Establishment
The development of Inkerman Mill was closely associated with John Drysdale, who had played a major role in the development of Pioneer Mill and irrigation agriculture in the Lower Burdekin.
In 1910, Drysdale acquired approximately 1,280 acres south of the Burdekin River. The Queensland Government was at the time subdividing the former Inkerman pastoral estate for closer settlement, creating the prospect of a substantial new cane-growing district.[2]
Drysdale negotiated with the Queensland Government over transport infrastructure, undertaking to establish a sugar mill if railway access and a bridge across the Burdekin River were provided.
Construction took place during 1913–14.
The mill was designed and built by Scottish engineer J. Pickering under Drysdale's direction, using machinery manufactured by George Fletcher and Company of Derby, England.[3]
Inkerman commenced crushing in 1914.[1][4]
Contemporary and later records place the first-season crush at approximately 62,000 tonnes of cane.
The severe Lower Burdekin drought of 1915 devastated the newly developed Inkerman cane area and the mill did not operate during that season.
Home Hill
The establishment of Inkerman Mill was closely linked with the development of Home Hill.
The Queensland Government had repurchased and subdivided the former Inkerman pastoral estate for agricultural settlement, while the railway connection south from Ayr was completed in 1913.
A township was surveyed near the mill to serve the rapidly growing farming population. Originally named Holme Hill, it was soon renamed Home Hill.
Employment at the mill and the expansion of irrigated cane farming subsequently became central to the development of the town.[5]
Pioneer Sugar Mills Limited
On 25 September 1914, Pioneer Sugar Mills Limited was formed and took over both Pioneer Mill and Inkerman Mill.[2]
The two factories remained under common ownership for most of the twentieth century.
Pioneer Sugar Mills became a public company in 1960 and continued to modernise both factories.
During the post-war period Inkerman underwent extensive expansion as irrigated cane production increased south of the Burdekin River.
A second milling train was installed during the 1970s, substantially increasing the factory's crushing capacity.
CSR ownership
In 1987, CSR acquired Pioneer Sugar Mills Limited, including Pioneer, Inkerman and Plane Creek Mill.[6]
Inkerman subsequently became part of CSR's Queensland sugar milling operations.
Wilmar ownership
CSR later reorganised its sugar and renewable energy operations under the Sucrogen name.
In 2010, Sucrogen was acquired by Wilmar International for an enterprise value of $1.75 billion. The Australian milling business was subsequently renamed Wilmar Sugar Australia.
Inkerman remains one of Wilmar's four Burdekin mills.
The mill celebrated its centenary in 2014.[1]
Infrastructure
Milling
Inkerman is a dual-milling-train factory.
Wilmar states that the mill processes an average of approximately 1.7 million tonnes of sugarcane each year and manufactures about 260,000 tonnes of raw sugar.[1]
Inkerman is also unusual in using a cane diffuser as part of the extraction process.
Wilmar identifies Inkerman and Invicta Mill as the only two Australian sugar mills currently using diffusers.[7]
In a conventional milling train, shredded cane passes through a series of crushing mills. At Inkerman, the diffuser replaces several of the intermediate crushing units. Shredded cane forms a moving fibre bed through which water is repeatedly percolated to wash sucrose from the fibre.
Cane railway
Inkerman operates a 610 mm (2 ft) gauge cane railway serving the southern Burdekin cane-growing districts, including Home Hill, Kirknie, Iona, Osborne and surrounding areas.
The modern network is physically isolated from the interconnected Invicta, Pioneer and Kalamia cane railway systems north of the Burdekin River.
There is no permanent 610 mm gauge cane railway crossing of the Burdekin River.
This isolation occasionally requires unusual transfer arrangements. During the 2020 season, cane was transferred from the Inkerman system to Invicta by loading full cane bins onto road vehicles for transport across the river before they were returned to rail on the northern side.[8]
Historical 1,067 mm railway
Although Inkerman's principal cane railway has always been 610 mm gauge, the mill historically also operated a 1,067 mm (3 ft 6 in) gauge locomotive.
Inkerman No. 1 was a Hunslet 0-6-0T steam locomotive, works number 1119 of 1913.[9]
The locomotive was used to haul cane across the Burdekin River over the Queensland Government railway and was subsequently retained for shunting 1,067 mm gauge exchange traffic associated with raw sugar and molasses.[10]
By the late 1960s, Inkerman No. 1 was primarily used to shunt Queensland Rail bulk sugar and molasses wagons between the mill and the nearby railway interchange.
The locomotive was later preserved.
Raw sugar transport
Finished raw sugar from Inkerman is loaded into 1,067 mm gauge heavy-rail wagons and transported north to the Townsville Bulk Sugar Terminal.
All four Wilmar Burdekin mills use Townsville as their raw sugar export terminal.[11]
Locomotive fleet renewal
Wilmar undertook a significant renewal of the Inkerman locomotive fleet ahead of the 2024 crushing season.
A new 26-tonne Alma was delivered to Inkerman in March 2024. The locomotive was designed and built by Wilmar's own engineering workshops and was based on the Brisbane locomotive introduced in the Herbert district the previous year.[12]
Wilmar described Alma as the first new-model locomotive commissioned for Inkerman since Iyah in 1976.
A second new 26-tonne locomotive, Kirknie, was also allocated to Inkerman for the 2024 season.
The new locomotives formed part of a wider Wilmar program involving four new locomotives and two brake wagons.
The 2024 Alma should not be confused with an earlier Inkerman locomotive of the same name. The original Alma was Commonwealth Engineering locomotive FE56110, built in 1975.[13]
Production statistics
Wilmar publishes Inkerman's long-term average production as approximately 1.7 million tonnes of cane and 260,000 tonnes of raw sugar per year.[1]
