I happen to live in Denmark, and I clearly remember when this happened :

For days I was actually in a state of chock, because I had not in my wildest nightmares imagined that this could happen.
Even though I had been away from $cn for more than 10 years at that time, I still had relatives in there, and some of them just had to be very close to what happened.
I don't know what happened later on with the canadian Hiver parents, and the Nanny was probably sentenced to some kind of psychiatric treatment. She's probably no longer in Denmark.
Some years ago I was contacted by Andreas from OCMB, who had been asked by some Hiver-relatives from Canada if he possibly could trace the Nanny. I tried to help, but had no chance through official channels, her name was Ludmila Vassilieva.
I don't know if this can be of any use for the Australia-matters, but I think it gives just another good picture of how irresponsible such matters as child-care are taken care of in this so-called "church".
