Senator JOYCE (Queensland—Leader of The Nationals in the Senate) (14:16): Mr President, I ask a supplementary question. I refer the minister to the updated NBN Co. corporate plan that the government released last week, which revealed a $5 billion blow-out in the net cost of the NBN. Given that the government will be required to borrow more debt to provide to the NBN, can the minister advise the Senate what the value of the outstanding Commonwealth government securities will be at the end of this financial year and at the end of the next three financial years?
