I refer the Prime Minister to his answer to my previous question and to his going on television earlier this year to urge Australians to invest in the National Broadband Network, which he said would be commercially viable. Will the Prime Minister, having had some time to think about it, now answer these questions: what will it cost, how many subscribers will it have, what will they be asked to pay, and, if it is going to be able to pay interest on the bonds you are urging people to buy in it, what will its net revenues be?
