In question time today, the Prime Minister made the claim that I'd divulged classified information. This is an incredibly serious and blatantly irresponsible assertion to make. It is blatantly untrue. I'm sure the Prime Minister knows that too. I have been, and continue to be, in regular contact with our security agencies. I treat the briefings that they provide to me seriously and with confidentiality. Senator Dastyari has made it publicly clear he's never had access to any classified information.
