Mr ABBOTT (Warringah—Leader of the Opposition) (14:01): My question is to the Prime Minister. I remind the Prime Minister that every time the government has increased the government credit card limit since it came to office—from $75 billion to $200 billion to $250 billion and, most recently, to $300 billion—it has fully utilised the increase. I ask the Prime Minister: will she now rule out trying to increase the nation's credit card limit above $300 billion in the May budget?
