It is awful and will lead to the further breakdown of our dairy industry.
I'm not sure what consumers can do. Most of the major milk brands are owned by this corporation.
Remember that, at the bottom of this chain are little dairy farmers who have little control or impact. I used to to work in a dairy area and dairy farmers lives have been gradually eaten away at since deregulation.

I buy a mix of Aussie Farmers Direct and Maleny Dairies (my absolute favourite - gorgeous milk and sooooo creamy, as well as being a small family company).
