RADIO host Michael Christian, one of two Southern Cross Austereo presenters at the centre of a disastrous royal prank that ended with the suicide of a British nurse, has resumed work.
Christian went to air on Monday as a presenter of Melbourne's morning slot on the Southern Cross Austereo station Fox FM.
It is the station and slot Christian worked on before the prank. At the time of the prank, Christian and another Southern Cross Austereo presenter, Mel Greig, were working as summer hosts of a national show, the Hot30 Countdown.
The pair have been off air since the royal prank made international news.
The duo telephoned London's King Edward VII's Hospital in December pretending to be the Queen and Prince Charles, inquiring about the condition of the Duchess of Cambridge, who had been hospitalised in the early stages of her pregnancy.
They duped two members of the hospital staff into divulging private information about the Duchess's condition.
In its aftermath, one of the nurses, Jacintha Saldanha, committed suicide.
Southern Cross Austereo immediately suspended the pair and offered them counselling.
Many blamed the pair for the nurse's death and Southern Cross Austereo was heavily criticised for encouraging a culture of misbehaviour by its hosts to drive ratings.
''If we played any involvement in her death, then we're very sorry for that,'' Christian later said in a TV interview.
Southern Cross Austereo cancelled the Hot30 Countdown and then implemented a company-wide suspension of prank calls.
A spokesman for Southern Cross Austereo confirmed Christian was back at work and that, when she felt able, Greig would also be welcomed back to work.
