$56bn needed in 2010/11 12 May 2010 4:25PM Ian Rogers The face value of Treasury Bonds on issue at 30 June 2010 is projected to be around $125 billion. The Australian government said it expects to sell around $56 billion in Treasury bonds during the 2010/11 year to cover the expected budget deficit of $41 billion, repayment of maturing bonds and incidental management of liabilities.A token number of Treasury bonds sold may be branded as Aussie Infrastructure Bonds and linked to the funding needs of the government-owned company building a new broadband network. Most of these bonds - which the budget paper suggests will be around $300 million - will still be sold to institutional investors.The budget papers show that Treasury estimates the level of net debt in 2010/11 at $78.5 billion, which is $33.7 billion lower than estimated in the 2009/10 Budget. Net debt is now expected to peak at 6.1 per cent of GDP in 2011/12 and decline to around $90.8 billion (and around 5.5 per cent of GDP) in 2013/14.
