Don’t laugh too hard at the ABC’s new satire, Utopia, and the wasteful and appearances-driven antics Rob Sitch gets up to as head of the Nation Building Authority. It’s too close to the truth to be funny.

One of the foremost areas where governments need to lift the efficiency of their spending - as opposed to cutting payments to the needy or short-sighted cost-shifting - is infrastructure. It has become an area where too much spending is never enough and anything labelled “infrastructure” is above critical scrutiny.

In recent days, however, we’ve been given cause to cast a more sceptical eye over spending on capital works. Consider first the views of a highly experienced former econocrat, Dr Mike Keating: “Australia has a long history of over-investment in infrastructure, with the costs exceeding the benefits, and under-charging the beneficiaries so that they demand more and more.

“It is therefore most reprehensible that this budget prides itself that new spending decisions will add $58 billion to total infrastructure investment, when none of the projects announced has been ticked off by Infrastructure Australia as having completed proper cost-benefit appraisals; probably because a great deal of this investment never could pass any proper evaluation.

“And this from a government that was properly critical of the former government and its approach to the national broadband network. Clearly this improper use of the nation’s savings is not an acceptable reason for the other budget cuts, and the increase in petrol excise should not be tied to an increase in uneconomic road funding.”
