The company originated in the Riverina District of Southern New South Wales in 1927 adjacent to the Wise Brothers flour mill in the township of Narrandera.
In 1955 the company’s manufacturing activities extended to Queensland and during the subsequent years business grew to service both domestic and overseas markets with a complete range of compound stock feeds and feed ingredients.
In February 1988 the company was re-structured with the involvement of Mitsubishi Corporation as a shareholder. This association has assisted in expanding markets both within Australia and overseas.
During the 1990’s the company grew its processing operations with the addition of the Leeton branch in NSW (1990). In 1995 Mitsubishi Corporation became 100% owner of the company and in that same year a suspension supplement plant in Warwick, QLD (1995) was commissioned. Two years later a modern feed mill was established in Casino, NSW (1997) which catered to a growing broiler industry
The expansion continued in the 2000’s to include the acquisition of the Murgon feedmill (2005), a second suspension plant in Mackay (2006), and Oakey Mill (2010).
By 2017 a merger between AGREX AUSTRALIA (Mitsubishi Corporation owned grain trading entity) and RIVERINA AUSTRALIA completes the story to date. The merger has boosted the Riverina grain trading and export business to new levels. Nowadays Riverina is an active shareholder in Newcastle Agri Terminal exporting bulk grain to many parts of the globe, has five grain based feedmills and two liquid suspension plants.
