Short Story
(about a new milk road)
Like most Australians since first fleet, you probably started life on milk directly from your mother on the day you were born.

Your second step or so in life's food chain was likely cow milk from dairy farmers.

It came from the same farmers who sold milk to your neighbours too.

Milk was delivered right down the road, directly on to your doorstep.

Many of these farmers had migrated to Australia & New Zealand from other English-speaking cultures like the UK.

When they had extra milk, it was sold to back to countries & cultures from where they themselves or their families had migrated, such as Europe or the UK.

But then one day a country in Asia with a very large population grew their economy from small to big.

Consumers there wanted milk from Australia too.

So people started building roads to move milk there.

And that created more change in different ways than most people expected, especially for the farmers who continued to supply the milk.

That's a simple story of how a new milk road naturally developed between Australia and Asia.

It also helps explains why Australia depends on its new "milk road economy" with its largest trade partner in Asia.

Bain & Co conducted a study that's a useful reminder that safe milk represents value, especially when it's not easy to get.
