Co-operatives Australia has published a 2nd top 100 list of co-operatives, credit unions and mutuals by annual turnover. Industries represented in the top 100 list include agriculture, financial services, insurance and retailing. The list demonstrates the economic and social impact of social businesses in Australia – part of a fourth sector which generates in excess of $14.5 billion in turnover in a year. The list demonstrates that co-operatives, credit unions and mutuals are a viable alternative to private and public enterprise . Yet, it is a scope and significance that is not readily understood and accepted.
