During a period of seven years spanning much of the Great Depression, 1929 –36, Clary Hill & Co. introduced a number of significant innovations to Australian rural grocery retailing in the Riverina district of New South Wales, Australia. An approach to business which owes much to Clary and Elsie Hill’s ethical beliefs, a dynamic, forward looking approach to technology, and a willingness to try new business models and methods saw two particular innovations which appear to have been radical for their time and location. The first is the use of long distance haulage via semi-trailer trucks in supply logistics. The second is the use of a ‘cash-and-carry’ retail model that presages ‘self service’ and the modern supermarket, at a date well before other reported similar innovations in this area. The paper offers an example of historical research of a type that may help overcome an evident gap in our knowledge of the development of grocery retailing in Australia.
