The National Association of Retail Grocers of Australia (NARGA), which represents more than 4000 independent operators, has made a submission to a federal government review of the Trade Practices Act demanding stronger laws governing anti-competitive behaviour. NARGA spokesman Alan McKenzie said that independent grocers and supermarkets are under pressure from big business' predatory pricing strategies: "NARGA has no problem with vigorous competition. Our problem is where that competition is unfair."
