Supermarkets build market shareBy the early ’70s supermarkets had 50% share of the grocery market, a substantial increase since 1968-69, when a third of the groceries in Australia were sold in supermarkets. Five years later, this had increased to half.  In 1973, Woolworths had 20% of the Australian grocery market, followed by Coles with 14%. The Davids groupwhich included Supa Valu and Foodland, had 5%, Franklins had 4%, and the Western Australian group FAL 1%. The remaining  55% was shared by other retailers.
