Mr IAN MACFARLANE (Groom) (14:19): My question is to the Treasurer. I remind the Treasurer of his statement on Friday that the mining tax failed to raise enough revenue because: Iron ore prices fell … So a very dramatic drop in commodity prices reflected in a drop in revenue. Is the Treasurer aware that iron ore spot prices have in fact increased by about $30 a tonne since his own budget outlook, an increase of almost 25 per cent?
