Mr SHORTEN (Maribyrnong—Leader of the Opposition) (15:06): My question is to the Prime Minister. Under this Prime Minister, gross debt has crashed through a record half a trillion dollars. Does the Prime Minister agree that Australia has very high levels of debt and very high asset prices? Does the Prime Minister agree that this is the No. 1 domestic risk to our economy? Isn't this the worst possible time to lock in a 10-year $80 billion business tax giveaway, fuelling national debt?
