Senator RHIANNON (New South Wales) (14:49): Mr President, I ask a supplementary question. Could the minister— Government senators interjecting— The PRESIDENT: Order! On my right. I need to hear the question. Senator RHIANNON: Could the minister answer this question rather than go into her bombastic abuse mode. Considering Infrastructure Australia's assessment shows that the WestConnex business case wrongly estimated project costs because they did not follow the guidelines, resulting in a potential cost blow-out of hundreds of millions of dollars, does the minister now accept that it would be a better use of money to invest in public transport to reduce traffic on Sydney roads and fix congestion in the long term?
