Arnott's, in common with the majority of Australian biscuit manufacturers, operated primarily in its home state, New South Wales, but has manufacturing plants in Virginia, Queensland (manufactures only plain, cream and savoury biscuits) and Shepparton, Victoria. In 1949 it merged with Morrows Pty Ltd, a Brisbane biscuit manufacturer, forming William Arnotts, Morrow Pty Ltd. In the 1960s, a series of amalgamations and acquisitions in the Australian market resulted in the creation of the Australian Biscuit Company Pty Ltd. This included Arnotts and other companies such as Brockhoff Biscuits, Arnott-Motteram and Menz in South Australia, and Guest's Biscuits in Victoria, and Mills and Ware Ltd in Western Australia. The Australian Biscuit Company was later renamed Arnott's Biscuits Pty Ltd. Regional varieties were maintained after these mergers, such as Menz Yo-Yo, Brockhoff Salada and Guest's Teddy Bears.
