Senator PRATT (Western Australia) (14:00): My question is to the Attorney-General, Senator Cash. In an article this morning in the Australian titled 'Feds muscle up on borders', the Attorney-General warned state governments they may once again face High Court challenges to force their borders open. Given the Morrison-Joyce government has now spent more than $1 million— Government senators interjecting— The PRESIDENT: Order. Sorry, Senator Pratt. On my right: I have repeatedly asked for silence during questions. Could you commence from the word 'Given', Senator Pratt. I got the preface to the question. Senator PRATT: Given the Morrison-Joyce government has spent more than $1 million of taxpayers' money supporting Clive Palmer's High Court challenge to the Western Australian borders, will the minister now guarantee that the Morrison-Joyce government will not spend any more taxpayers' money on challenging Western Australia's border decisions?
