Senator CASH (Western Australia—Attorney-General, Minister for Industrial Relations and Deputy Leader of the Government in the Senate) (14:03): Let me make it clear again to Senator Pratt: the Commonwealth will not challenge Western Australia's border closures in the High Court and we will not support any challenge to Western Australia's border closures by Clive Palmer. What we are doing, though, is working with the states and territories in relation to the implementation of the national plan. And in Western Australia, I understand, we've now reached 50 per cent of Western Australians having had their first dose. That is actually a good thing. And very shortly you'll get to 60 per cent, then 70 per cent and then 80 per cent, and, once we are at 80 per cent, the question does become: what do we all do at 80 per cent? But we are working with the states and territories, as agreed, through the national cabinet, to implement the national plan for reopening. Honourable senators interjecting— The PRESIDENT: Order, on my left and right. Order. Senator Pratt, a final supplementary question?
