The dispute of one of the Australian DJs who caused a nurse to commit suicide as a result of the infamous royal prank call has been resolved, South Cross Austereo said in a statement on Thursday.

DJ Mel Greig filed in July with Fair Work Australia a complaint that the radio station was not a safe workplace because of its prank call feature that eventually cost the life of Jacintha Saldanha, an India-born nurse who worked at the King Edward VII Hospital in London. She mistakenly provided information about the medical condition of Kate Middleton, then pregnant with her first baby, thinking it was Queen Elizabeth who was inquiring on the other end of the line.

The radio station insisted that recording and broadcasting the notorious call was not illegal and 2Day FM aired the call without alteration, even if Ms Greig suggested it be changed before it was broadcast.

With its stand, the station absolved Ms Greig of responsibility for the decision to broadcast the prank call, despite her suggestion to change it. At the same time, the company reiterated it greatly regrets the tragic result of its prank and have given a substantial sum for a trust established to assist the deceased nurse's family in India.

The station said with Ms Greig's resignation effective Dec 31, the dispute is amicably resolved.

Michael Christian, the other DJ who mimicked the voice of Prince Charles in the prank call, is back on air and was name in June as the station's top DJ.
