Senator BACK (Western Australia—Deputy Opposition Whip in the Senate) (14:05): Mr President, I ask a further supplementary question. The last time the Prime Minister visited was 13 November 2012. Is the reason the Prime Minister has been asked to stay as far away as possible from Western Australia that Mark McGowan has condemned the government's carbon tax and mining tax? If the state Labor Party can recognise that these toxic taxes are bad for Western Australia, when will federal Labor wake up to the fact that they are dangerous to the Australian economy? Honourable senators interjecting— The PRESIDENT: Order! Those at the front of the chamber, order! Senator CONROY: Again, what we see from those opposite is that Barnett-Liberal Party mining taxes are good because the Liberal Party has introduced them. They are good; they are fine; they are all wonderful things. But if the government introduces a tax that is fair for all Australians, then suddenly it is bad. So we have the Liberal Party taxing mining companies is good and to be supported; Labor Party raising taxes on mining companies to spread across the country is bad. The grovelling attitude by those opposite is just nauseating to witness. Liberal Party mining taxes are good—that is okay, all across the country: New South Wales, Queensland, Western Australia. The Prime Minister will continue to campaign the length and breadth of this country about investing in our mental health: $2.2 billion— (Time expired)
