Casey Treloar, from South Australia, told Tom Elliott she posted the video because she wanted the everyday Australian to know what dairy farmers are really dealing with.

“Our story isn’t the only one,” Casey said.

“Family dairy farms are dropping like flies.

“Coles and Woolworths have a lot of power in their hands, if they turned around upped the price of their milk and said we’re going to ensure that goes back through to the farmers, we’ll see a big rush of support.

“It’s difficult.

“At the same time, it’s no good putting all the local producers out of business.

“There’s a problem here. How do we fix it?”
