Coles protest

In February Woolworths bumped up the cost of its own-brand milk by 10¢/litre, with the money to go to drought-affected farmers.

However, Coles refused to follow suit over concerns it would impact customers struggling with the cost of living.

It said at the time it would look at other ways to help farmers, including collecting customer donations and matching them dollar for dollar.

Coles’ decision not to boost milk prices drew the ire of Federal Agriculture Minister David Littleproud, who urged customers to boycott the supermarket.
