We begin with the australian z deejays speaking out for the first time. Cecilia vega is in sydney with the latest. Good morning. Reporter: George, good morning to you. They say this was supposed to be a simple, harmless prank that lasted no more than 30 seconds. They thought they would be hung up on immediately. We all know that is far from what happened. Personally I'm -- Reporter: The two australian deejays behind the phony phone call came out of hiding overnight. Offering a tearful apology to the family of the nurse. Shattered, gutted, heart broken. Incredibly sorry for this situation and what's happened. There's not a minute that goes by that we don't think about her family and what they must be going through. The thought that we may have played a part in that is -- hello, there, could I please speak to kate, please, my Oh, yes, hold on, ma'am. Reporter: They said they never imagined they would get through to the hospital where kate middleton was rekefri irecovering from severe morningsickness. They never could have predicted that days later, skra sin that is -- jacintha ldanha would be found dead of an apparent suicide. We both found out about the same time. I think it was -- the worst phone call I have ever had in my life. Reporter: The global backlash has been fierce. The radio station announced it's banning phonemy phone calls altogether and suspending advertising indefinitely. The team is off the air. One final thing to say. I wanted to reach out to them and give them a big hug and say, sorry. I hope they're okay. I really do. Reporter: Higher ups at the station made the final decision to air the call. Lawyers were involved in that. Not once in this interview did the deejays express reservation about airing their prank.
