Talking about the call on air Thursday, Greig said: "They were the world's worst accents ever. We were sure 100 people at least before us would've tried the same thing. ... We were expecting to be hung up on -- we didn't even know what to say when we got through."

Angry comments have been posted on the 2Day FM Facebook page since the news of the nurse's death broke.

"This death is on your conscience," reads one post. Another says, "Blood on your hands."

In the immediate aftermath of the prank and well before the nurse's suicide, the radio station's Web page saw equally outraged comments from listeners, and they outnumbered postings from those who liked the hoax.

"Your stunt was done at a time in this country where there is paranoia about the intrusion of the media into people's lives," Gary Slenders wrote. "I know you will say it is harmless fun, the management of 2DayFM will say that it won't happen again, but this exactly where the phone hacking scandal started."

There were some immediate supporters of the prank, however.

"It is only a joke people! it was great i love it!!!" wrote one listener who identified himself as Guido.

But after news of the nurse's suicide circulated, the public comments on the radio station's Web page became outraged.

"This pair have undone all the good work Australia have done in the last century," a person named Riz wrote. "The Australian people should be outraged at the pair of them. They've brought disgrace on your country - and the whole world knows it!"

"Not so funny now is it," Heather wrote. "This will darken the whole pregnancy experience for William and Kate. Before you do these thoughtless, ignorant - UN-funny things, remember -- God is watching you."
