"So only $7 billion comes off general government debt," he said. University of Queensland economist John Quiggin.

Rather than looking at general government debt, which has to be serviced out of tax revenue, they have been lumping that in with the debt held by the government-owned corporations, which is serviced out of their earnings. "A GOC debt, like that from a company like Energex, is paid out of Energex's earnings, so there is no cost to taxpayers, and we have an asset. A general government debt is used to finance things like schools and hospitals and has to be paid for, has to be serviced out of tax revenue." However, Treasurer Tim Nicholls said ratings agencies took into account total debt when assigning a credit rating.

"Even Professor Quiggin admits debt is a problem and he's very clear in his view that higher taxes for Queensland families is the answer," he said. "This report challenges Labor to say which taxes they increase in order to pay down debt. "After six days of campaigning we still haven't seen any detailed costings or economic plan from Labor. Uncertainty and chaos seem to be the hallmarks of their promises to date." Professor Quiggin said the assets earmarked for privatisation – labelled a long-term lease by a government desperate to avoid the word 'sale' in its campaign materials, currently provide $1 billion a year to the state, a figure he said would grow. By comparison, he estimated interest savings to the general government sector would be between $200 and $300 million a year. "The majority of net proceeds are allocated to non-commercial infrastructure investments and subsidies for electricity consumption," he concluded in his report.

"Only around $7 billion will be available to repay general government debt. "As a result, the interest savings from privatisation fall far short of the foregone dividends and tax equivalent payments. The loss will grow over time. "Based on the government's own projections of GOC earnings, the adverse impact will be around $2 billion a year by the end of the forward estimates period. "The cumulative loss will be around $9 billion by 2020. "The [Strong Choices] Plan will reduce the government's net worth by $8 billion to $10 billion over the same period.

"The claimed job creation benefits are temporary and far outweighed by previous cuts. "Public expenditure, including the provision of non-commercial public infrastructure, must be financed primarily through taxation. Governments that evade this reality are exhibiting weakness, not strength." Premier Campbell Newman is set to announce infrastructure promises on the campaign trail on Monday. Professor Quiggin has long argued the privatisation of the state's assets does not make economic sense, an argument he also made when the Labor government off-loaded assets including QR National. He referred to the $3.4 billion cost of living fund as "political pork barrelling" .

"The problem is particularly severe when the source of finance is a pot of 'free money', such as the proceeds of asset sales, which can be allocated without going through normal budget processes," he said. Professor Quiggin said while the government argued that increasing tax revenue, reducing public expenditure or tolerating the debt was not acceptable, "in reality, asset sales and leases make little difference to the fiscal positions of governments", even when optimally managed. "When the proceeds are dissipated on politically motivated projects, as in the present cases, privatisation makes governments worse off," he said. "... Unfortunately, successive Queensland governments have maintained the fiction that we can be a low-tax state while still providing the same public services and high-quality infrastructure as other states. "Until this delusion is abandoned, we will experience financial difficulties whenever government revenue experiences one of its regular cyclical declines, as is happening at present."
