Overview
Manildra Group is an Australian family-owned agribusiness headquartered in Sydney, New South Wales. Its origins lie in flour milling: in 1952, Dick Honan acquired a flour mill in the regional New South Wales town of Manildra, establishing the business from which the group takes its name. Over subsequent decades, the company expanded from conventional flour production into a broader agricultural-processing portfolio built around wheat, grain and other agricultural commodities. A significant turning point came in 1966, when Manildra established a starch and gluten plant at Auburn. This move broadened the business beyond flour and gave it a role in producing functional ingredients used by food and industrial customers. During the early 1970s, the group extended its starch-processing footprint with plants at Bomaderry in New South Wales and Devonport in Tasmania. It also established a glucose plant at Bomaderry and acquired a flour mill at Gunnedah, further increasing its grain-processing capacity and geographic reach. In 1985, the Auburn plant was closed and its operations were transferred to Bomaderry. Bomaderry subsequently became an important center for the group's starch, glucose and later ethanol activities. Ethanol production began there in 1991, adding biofuel production to Manildra's existing food-ingredient and milling operations. The combination of flour milling, starches, gluten, glucose and ethanol reflects an integrated processing model in which agricultural raw materials can be directed into multiple food, industrial and energy products. Manildra diversified again in July 2014 by purchasing an abattoir in Cootamundra, New South Wales. The acquisition marked an expansion into meat production and demonstrated that the group was no longer limited to grain-based processing. Its broader activities have also included participation in sugar through Sunshine Sugar, a partnership between the grower-owned New South Wales Sugar Milling Co-operative and Manildra Group. The group remains privately held and family owned. Its operations are associated primarily with Australia, while its products and ingredients serve international markets. In 2021, Manildra was placed 29th in FoodTalks' ranking of leading global specialty-oil companies, indicating recognition of part of its wider agricultural-processing portfolio. The ranking does not by itself establish the group's total revenue or market position across all of its businesses. Manildra has also faced operational and environmental scrutiny. In October 2024, two grain silos at the group's Shoalhaven Starches plant in Bomaderry collapsed, releasing grain into the Shoalhaven River and prompting an emergency response. The available reference material states that the incident caused no significant environmental harm to the river. The New South Wales Environment Protection Authority nevertheless required Shoalhaven Starches to provide more than A$170,000 for local environmental projects and to carry out an environmental hazard analysis intended to reduce the risk of similar incidents. This event is part of the group's recent public record but does not change its continuing status as an active agribusiness.
History
Manildra Group began in 1952 when Dick Honan purchased a flour mill in Manildra, a regional town in New South Wales. The original business was centered on flour milling and the processing of grain for food use. The acquisition provided the foundation for a family-owned enterprise that later expanded into a range of agricultural-processing activities. The company's first major diversification occurred in 1966 with the establishment of a starch and gluten plant at Auburn. Starch and gluten production enabled Manildra to serve food and industrial customers with ingredients that were distinct from standard flour products. In the early 1970s, the group continued to expand its processing network. It opened additional starch plants at Bomaderry in New South Wales and Devonport in Tasmania, established a glucose plant at Bomaderry, and purchased a flour mill in Gunnedah. These developments created a geographically distributed milling and ingredient-processing operation. Bomaderry became particularly important as the company consolidated activities there. In 1985, Manildra closed its Auburn plant and transferred operations to Bomaderry. The change concentrated starch-related production at the Shoalhaven facility while maintaining the group's wider network of mills and processing sites. Manildra entered ethanol production at Bomaderry in 1991. Ethanol added an energy and industrial dimension to a business previously best known for flour, starch and gluten. The group's product mix consequently came to include food ingredients, glucose and biofuel, illustrating the use of agricultural commodities across multiple end markets. The next major strategic expansion came in July 2014, when Manildra purchased an abattoir in Cootamundra. The transaction diversified the company into meat production and processing rather than simply extending its existing grain operations. Manildra has also participated in the sugar industry through Sunshine Sugar, a partnership with the grower-owned New South Wales Sugar Milling Co-operative. This partnership connected the group with sugar milling and related agricultural supply chains. In 2021, FoodTalks ranked Manildra 29th among global specialty-oil companies. The recognition reflected the group's participation in specialty agricultural and food-processing markets, although the available material does not provide a detailed breakdown of the relevant products, sales or geographic shares. In October 2024, two grain silos at the Shoalhaven Starches plant in Bomaderry collapsed. Grain entered the Shoalhaven River and an emergency response followed. The available account records no significant environmental harm to the river, but the New South Wales Environment Protection Authority imposed follow-up requirements. Shoalhaven Starches was directed to fund more than A$170,000 in local environmental projects and to undertake an environmental hazard analysis designed to prevent or mitigate comparable incidents. Across its history, Manildra Group has therefore evolved from a single flour mill into a diversified Australian agribusiness. Its documented activities span flour milling, starch and gluten, glucose, ethanol, meat processing and sugar-related operations. The group remains privately held and family owned, with Sydney as its headquarters and production assets concentrated in Australia.

Products and positioning
An Australian family-owned, vertically diversified agribusiness that converts agricultural commodities into food ingredients, industrial materials, biofuels and food products.
Milling · 1952
Flour
Flour milling is the historical foundation of Manildra Group. The business began with a mill at Manildra and later expanded its milling network through the acquisition of a Gunnedah mill. Flour remains part of the group's broader grain-processing portfolio, alongside starch, gluten and glucose products.
Food and industrial ingredients · 1966
Wheat starch
Manildra developed starch production as a major diversification from flour milling. Starch plants were established at Auburn, Bomaderry and Devonport during the 1960s and early 1970s. After the Auburn facility closed, Bomaderry became the principal documented location for transferred starch operations.
Food ingredients · 1966
Wheat gluten
Gluten production began with the Auburn starch and gluten plant established in 1966. The ingredient-processing activity broadened Manildra's customer base beyond conventional flour buyers and became part of the group's integrated grain-processing model.
Food ingredients · 1970
Glucose
The group established a glucose plant at Bomaderry during its early-1970s expansion. Glucose production added another processed ingredient to Manildra's portfolio and complemented the group's starch-processing operations.
Biofuels · 1991
Ethanol
Manildra began ethanol production at Bomaderry in 1991. Ethanol represents the group's move into biofuel and industrial production, extending the use of agricultural raw materials beyond food ingredients and milling.
Meat processing · 2014
Meat products
Manildra entered meat production through its July 2014 purchase of an abattoir in Cootamundra, New South Wales. This operation expanded the group into livestock processing and added a non-grain business to its agricultural portfolio.
Sugar
Sugar-related products
Through Sunshine Sugar, Manildra Group participates in a partnership with the grower-owned New South Wales Sugar Milling Co-operative. The partnership connects the group with sugar milling and related products, although the available reference does not provide a detailed product catalogue.
