So, how could WA manage to make it through a once in a century commodity price spike and still not manage to deliver a surplus? Easy. They spent a fortune subsidising the mining industry.

Just last year the WA Treasury wrote to the commonwealth to explain how expensive it was to host the mining industry. Among other gems they wrote that "the cost of Western Australia's assistance to the North West Shelf project – e.g. payment of subsidies to the state's power utility to help cover the losses it initially incurred under crucial 'take or pay' gas contracts – is estimated to be around $8 billion."

The WA Treasury goes on to criticise the Commonwealth Grants Commission for dividing up the GST revenues between states on the basis that "it fails to equalise many state expenditures that support resource development, particularly provision of infrastructure". They openly describe government decisions to pay for much of the mining industry's infrastructure as "a significant subsidy cost".

The WA government has spent a fortune subsidising some of the world's biggest companies in the middle of a mining boom. Their own state budget papers show the cost to be around $6.2 billion over the past six years and their own Treasury calls such payments a subsidy.

WA's tantrum at COAG, combined with Tony Abbott's tenuous grip on power, has reportedly delivered a $600 million windfall to Western Australia. Just imagine if Jay Wetherill or Daniel Andrews spent a few billion dollars subsidising the car industry. Would their industry policy decisions be cross-subsidised by the other states, or by the Commonwealth?

Long run costs concealed

The temporary revenue boost from the mining boom allowed Peter Costello and Colin Barnett to conceal the long run costs of their worst decisions. Costello responded to a short term boost in company tax revenues by introducing permanent cuts to tax on capital gains, superannuation and personal income. Colin Barnett shovelled billions of taxpayers' dollars into mining infrastructure that optimistic miners should have funded themselves.

It is not the collapse of the mining boom that has broken state and federal governments; it was the inability of those who claim to manage our finances to see that what goes up, must come down.

But while our budgets can be easily repaired by ending the mining subsidies and closing the tax loopholes Peter Costello wove into our tax system, our system of federation may be harder to fix. The mining boom has highlighted the greed of some of our state siblings, and in turn the mining boom has probably made it harder to get them to work together in the future.
