CHRIS BISHOP (National): Just a couple of final questions in relation to the threshold for re-opening the bubble. I note the Minister said Ministers will need to be certain the outbreak in New South Wales and wider Australia is contained and also that remaining cases have to be generally linked. What does that mean in reality? Is the threshold for the reopening of the bubble zero cases across the whole of Australia, for example? Or, if it's not zero, what is a low number of cases? And will the Government approach it on a New Zealand to Australia level—i.e., viewing Australia as a whole entity? Or will it take a state by state approach; reopening, for example, to Queensland—to take Queensland, for example—if they get down to very few cases, even while New South Wales may have a few more?
