A discussion on what can be termed "A market failure in the Western Australian dairy industry" can be found here.
A long time ago in the year 2000, the dairy industry in Australia deregulated.
This affected the 7 previously separated industries in a number of ways
Far North Queensland,
South Australia and
in a number of ways in a number of ways.
For example -
In Western Australia at the time of deregulation (2000), the following products were manufactured.
Drinking milk (3 well maintained factories)
Ice-cream - World class factory producing domestically and exporting to Japan
2 Cheese factories, both old, one with whey drying facilities.
3 Old milk powder driers,
1 Butter maker
In 2017, the 3 drinking milk factories remain, one of which is for sale,
the 3 drinking milk factories remain, one of which is for sale,
Cheese, butter, Ice-cream and powder all have left the state. (note- one cheese factory - which does not have whey drying capacity could be restarted)
Consequently, all the cheese consumed by Western Australia's 2,600,000 people is brought in from out of state.
The numbers are large.
35,000 tonnes of Cheese,
10,000 tonnes of Butter,
46 million litres of Ice-cream.
These changes have taken place due to rational decisions by the processors but to the detriment of the local industry and populace.
Investopedia defines market failure as -
each individual makes the correct decision for him/herself, but those prove to be the wrong decisions for the group
