Minister for Immigration and Border Protection Peter Dutton. The song ended with Mr Dutton laughing. "It's beyond my comprehension that, that she has any credibility in any major issue pertaining to our country," Hadley said. "You know her well, Ray, you know her well," Mr Dutton said. The song was first played on Hadley's show in February 2014 and has been played on air a number of times since. It is one of more than two dozen tracks in the 'Ray Hadley Parody Jukebox'. Clive Palmer, Jacqui Lambie and Kevin Rudd also feature in the list.

During a Senate committee on Tuesday, Mr Pezzullo confirmed the unauthorised operation had occurred. During the interview, Hadley said the Greens were calling for an apology from Mr Dutton after he called her an "embarrassment to the country," relating to the claims of espionage. "Well, and wacky as well, I think I said that at the time," Mr Dutton replied. "Oh sorry, let me clarify that; so she's a wacky embarrassment to the country. Can I say that?" Hadley said.

"No question," Mr Dutton said. "I mean, she's written to me on some issues which are completely fanciful when you have a look at the facts and she's got a track record of making these things up," Mr Dutton said. "If there was an action by an individual, for which that individual's been counselled, nothing to do with the Australian government or some belief that she's been spied upon," Mr Dutton said. The Greens deputy leader Senator Larissa Waters said both men were involved in "sexist claptrap" by playing the song on air. "Unfortunately this sort of pathetic attack on a young woman doing her job exceedingly well in the Parliament just demonstrates what a problem with sexism we still have in the Parliament and sadly in the nation more broadly," Ms Waters said. Ms Hanson-Young said Mr Dutton was engaging in intimidation.

"It would be helpful if the minister spent more time cleaning up the child abuse inside his detention centres than trying to intimidate those who scrutinise the government's policies," she said. Last month Nationals deputy leader Barnaby Joyce asked Australia's media watchdog to investigate an interview in which radio announcer Kyle Sandilands called the Agriculture Minister "an insensitive wanker", "a disgrace" and a "gerbil of a thing" on air.
