With dairy farmers from Tongala to Taree ready to raid every Coles supermarket with pitchforks, the dominant Wesfarmers-owned grocer released an educational video last week to explain the impact of its $1 milk on the dairy industry. But the numbers are slipperier than a Macca's thickshake. The video claims that overall milk volumes have grown. But production of drinking milk in Australia is actually going down. Down Down in Coles' case. And 55 dairy farms in Queensland have closed since Coles introduced $1 milk on Australia Day 2011.
