Mr President, I ask a supplementary question. In light of President Obama’s promise to the American people of wireless broadband built by the private sector, and assuming that the ‘secret’ parts of NBN Co’s business plan do not show ‘secret’ benefits of fibre versus wireless, why is this government insisting on spending up to $43 billion mainly on fibre—fibre which is at risk from natural disasters, construction delays and cost blow-outs?
