South Johnstone Mill

South Johnstone Sugar Mill

Establishment and Government Control (1911 to 1927)

The South Johnstone Sugar Mill was established following the Sugar Works Act of 1911, which authorised the construction of central sugar mills to encourage settlement in North Queensland. A Royal Commission selected the site on the South Johnstone River due to the fertile soils of the surrounding district, including the Japoon Valley, Liverpool Creek, and Maria Creek areas.

Construction began in 1914 but faced significant delays due to the outbreak of World War I. A notable incident during construction involved the loss of critical machinery and Fowler steam locomotives, which were aboard a transport ship sunk by a German warship while en route from England. Management was forced to source replacement materials from within Australia, and the mill was largely built using day labour.

The mill crushed its first cane in October 1916 under government control. In its first season, which lasted until February 1917, the mill produced 4,729 tonnes of raw sugar.

The Cooperative Era (1927 to 2001)

Following a period of labour unrest and industrial disputes in the 1920s (including strikes related to Weil's disease), the mill was transferred to grower ownership. In 1927, the South Johnstone Co-operative Sugar Milling Association Limited was formed, marking the beginning of a long period of farmer control.

During this era, the mill acted as the economic anchor for the local township. The tramway network was expanded significantly to service soldier settlement farms in the El Arish area. By the 1970s, production had increased substantially, frequently exceeding 100,000 tonnes of sugar per season. The mill celebrated its 50th year as a cooperative in 1977.

However, the late 1990s brought financial difficulties caused by low global sugar prices, cyclones, and crop disease. In 2000, the mill struggled to remain solvent, and in 2001, the cooperative went into receivership.

Corporate Ownership (2001 to Present)

In 2001, Bundaberg Sugar acquired the South Johnstone mill from the receivers, ending 74 years of cooperative ownership. Bundaberg Sugar operated the mill for nearly a decade before entering a joint venture with the Maryborough Sugar Factory (MSF) in 2010.

This joint venture merged the operations of the South Johnstone, Mulgrave, Babinda, and Tableland mills. In 2011, MSF Sugar acquired 100 per cent ownership of the joint venture assets, making them the sole owner of South Johnstone. Shortly after, in 2012, MSF Sugar was itself acquired by the Thai sugar giant Mitr Phol.

Under MSF Sugar, the mill continues to operate, processing cane from the South Johnstone, Silkwood, Kurrimine Beach, and Japoon areas.

Tramway Operations

South Johnstone operates an extensive 610 mm gauge tramway network that is vital to its logistics. The network is historically significant as it connects with the Mourilyan Sugar Mill tramway system.

Key features of the tramway network include:

• The Japoon Line: A major branch servicing the Japoon Valley.
• Township Running: The main line runs directly through the centre of the South Johnstone township, a distinctive feature where cane trains share space with road traffic near the mill entry.
• Mourilyan Connection: Historically, the system connected to the Mourilyan Harbour line, facilitating the transport of raw sugar to the bulk terminals.

The fleet has historically comprised a mix of steam locomotives (in the early years) and diesel-hydraulic locomotives. Following the integration with MSF Sugar, the rolling stock has been managed alongside the Mulgrave mill fleet, though South Johnstone retains its own dedicated maintenance facilities.

Significant Events

• 1918 Cyclone: The mill and surrounding township were heavily damaged just two years after opening, leading to a rebuild that influenced the local architecture.
• World War I: Caused the loss of original rolling stock and machinery at sea.
• Cyclone Larry (2006) and Yasi (2011): Both cyclones caused extensive damage to the mill infrastructure and the cane crop, impacting throughput for subsequent seasons.
