Southern Region

The Southern Region encompasses Queensland's sugar-growing districts from Bundaberg and Childers south through the former Maryborough and Sunshine Coast milling areas to Rocky Point on the northern Gold Coast. The region once contained numerous plantation, juice and central mills, but successive consolidation and declining cane supply have reduced the industry to three operating raw sugar factories: Millaquin Mill, operated by Bundaberg Sugar; the grower-owned Isis Central Sugar Mill; and the family-owned Rocky Point Mill.

The Bundaberg and Isis districts are major irrigated cane-growing areas, while the former Maryborough and Sunshine Coast industries have undergone substantial contraction. The closure of both Bingera and Maryborough mills following the 2020 season represented the most recent major rationalisation of milling capacity in the region.

Bingera Mill (Closed)

Bingera Mill was established by the Gibson and Howes families in 1885 on the northern side of the Burnett River. It developed into one of the largest mills in the Bundaberg district and remained under family control until becoming part of Bundaberg Sugar in 1972.

Declining regional cane production led Bundaberg Sugar to close Bingera following the 2020 crushing season after 135 years of operation. All remaining Bundaberg Sugar cane is now crushed at Millaquin Mill. Portions of Bingera's former 610 mm gauge railway network remain in use to collect cane from districts north of the Burnett River.

Maryborough Mill (Closed)

The Maryborough Sugar Factory Company was established in 1894 and commenced sugar production in 1895. The mill subsequently became the principal processing factory for cane grown throughout the Maryborough and Fraser Coast districts.

In its later years the mill was operated by MSF Sugar, which became part of the Thai sugar group Mitr Phol in 2012. MSF announced in November 2020 that the 2020 crushing season would be the mill's last, ending 126 years of operation.

Cane production has continued in parts of the former Maryborough mill area. From 2021, substantial quantities of Fraser Coast cane have been transported north for crushing at Isis Central Sugar Mill. Cane is generally hauled by road from the Maryborough district to transfer facilities before completing its journey to Isis Central in cane railway bins.

Fairymead Mill (Closed)

The Fairymead plantation was developed by the Young family from 1880. Cane juice from the plantation was initially transported to Millaquin for processing, before Fairymead became a complete sugar mill in 1884.

The Young family developed Fairymead into one of the major sugar enterprises of the Bundaberg district and introduced a number of innovations in cane cultivation, harvesting and transport. Fairymead subsequently became part of Bundaberg Sugar.

Bundaberg Sugar announced the closure of Fairymead in February 2005 after declining cane supply made continued operation uneconomic. Former Fairymead cane was redistributed to Bingera and Millaquin, and portions of its cane railway system continued to be used after milling ceased.

Millaquin Mill

Millaquin commenced operations in 1882 on the southern side of the Burnett River. Originally established as a refinery receiving juice from numerous small plantation crushing mills, it progressively developed into a complete raw sugar factory during the early twentieth century.

Millaquin became part of Bundaberg Sugar in 1975. Following the closure of Fairymead in 2005 and Bingera in 2020, it became Bundaberg Sugar's sole operating mill and now processes the company's entire regional cane crop.

The Millaquin site also incorporates a sugar refinery producing refined sugar for domestic industrial, retail and hospitality markets.

Gin Gin Mill (Closed)

Gin Gin Mill was established at Wallaville as a Queensland Government central mill and commenced crushing in 1896. It came under co-operative grower ownership in 1927.

The mill was purchased by Gibson & Howes, owners of Bingera Mill, in 1965 and became part of Bundaberg Sugar when that company was formed in 1972.

Gin Gin closed following the 1974 crushing season. Its cane supply was transferred to Bingera and a 610 mm gauge railway connection was constructed between the former Gin Gin network at Wallaville and the Bingera system, allowing cane to be hauled directly to Bingera.

Qunaba Mill (Closed)

Qunaba Mill originated as the Mon Repos plantation and juice mill east of Bundaberg. The operation developed into a complete sugar mill during the 1880s.

In 1899 the Queensland National Bank acquired the Mon Repos mill and plantation and renamed the operation Qunaba, a name formed from the words QUeensland NAtional BAnk.

Qunaba later became part of the Millaquin and subsequently Bundaberg Sugar operations. The mill closed in 1985 as part of the rationalisation of the Bundaberg industry. Its cane supply area and railway network were divided between Millaquin Mill and Fairymead Mill.

Isis Central Mill

Isis Central commenced crushing on 7 September 1897 near Childers. Established by local cane growers with Queensland Government financial assistance, it remains locally owned through the Isis Central Sugar Mill Company Limited.

The factory became the sole operating mill in the Childers district following the closure of CSR's Childers Mill after the 1932 season.

Isis Central has expanded its supply area substantially in recent decades. A 39 kilometre cane railway extension from Cordalba to Wallaville was completed for the 2020 crushing season, while the closure of Maryborough Mill later that year resulted in large quantities of Fraser Coast cane being transferred to Isis for processing.

As of 2026, approximately 200 growers from the Fraser Coast through to the North Burnett supply Isis Central, making it Australia's last grower-owned sugar mill.

Childers Mill (Closed)

The Colonial Sugar Refining Company established Childers Mill at Huxley in 1894. The factory competed with the nearby Isis Central Mill for cane throughout the early twentieth century.

Declining cane supply and poor financial performance led CSR to decide in September 1932 that Childers would cease operations. The mill completed its final crushing season that year, with railway equipment and other assets progressively disposed of during 1933.

The closure left Isis Central Sugar Mill as the sole operating factory in the Childers district. Isis subsequently acquired portions of the former CSR tramway and water-supply infrastructure.

Moreton Central Mill (Closed)

The Moreton Central Sugar Mill Company was formed in December 1894 under the Queensland Government's Sugar Works Guarantee Act 1893. Construction of its factory at Nambour commenced in 1895 and the first cane crop was crushed in 1897.

Moreton Mill and its extensive 610 mm gauge cane railway became central to the development of Nambour and the surrounding Sunshine Coast hinterland sugar industry.

The mill completed its final crushing season on 4 December 2003 after 106 years of operation. The railway system was subsequently dismantled and the mill itself was demolished in 2006. A small number of remaining Sunshine Coast growers subsequently transported cane north to Maryborough Mill until that factory also closed in 2020.

Rocky Point Mill

Rocky Point Mill is located at Woongoolba on the northern Gold Coast. The Heck family established its sugar operation at Rocky Point in the late 1870s, with the mill traditionally dating its commencement of operations to 1879.

The mill remains owned by W.H. Heck & Sons Pty Ltd and is unusual in the modern Australian industry as a long-established family-owned sugar factory. It is also one of the few Australian mills relying entirely on road transport for its cane supply, its former 610 mm gauge tramway having closed in 1951.

Rocky Point also contains a 30 MW biomass cogeneration plant using bagasse and other biomass fuels to produce steam and electricity.

In 2026, approximately 50 district growers were notified that their cane supply agreements would terminate following the 2027 crushing season. The agreements remain in force for the 2026 and 2027 seasons. Although grower representatives have described the decision as signalling the end of milling at Rocky Point, mill owner David Heck had not formally confirmed permanent closure of the factory as of August 2026.
