I heard about this as well but I don't see how she and her co-host should be made accountable when we don't know about the mental history of the nurse that picked up the call...
You don't see how they can be held accountable you say? I can, so they can the rest of the world. Let me break it down for you.
She and her co host, as a result of their prank, are directly responsible for this lady, who has kids and a husband commiting suicide. Had they not done this 'prank' the woman would still be alive, and with her family at christmas. Some places are even reporting that they could face extradition on manslaughter charges, and to be honest I hope they do.
Utterly ridiculus thing they did, and some poor woman has lost her life as a result, this is why the world is outraged, and this is why they are calling for blood. Australia is also a commonwealth country and extradition from Australia to England would be a simple process.
What they have done, will make them hate figures for a long long time, regardless of who is a fan of hers because she was on the Amazing Race Australia, she has done something very very wrong.
Pretending to be a Royal like that is also treason to be honest. I don't think this story is over, and I hope the nurse gets justice.
