Senator McALLISTER (New South Wales—Deputy Opposition Whip in the Senate) (14:57): Mr President, I do have a further supplementary question. The government's former top digital adviser, Mr Paul Shetler, has slammed Centrelink's robo-debt mess. He says if Centrelink was operating in any sort of free market it would go out of business or, if it did not go out of business, it would be shut down by regulators for fraud. When is the minister going to swallow his pride and admit that the Centrelink robo-debt mess has to be fixed?
