I just want you to know that CI does not really help with group conversation or noisy background. I think your daughter will still have to do one-in-one conversation (that part of the deaf world so it is something you have to accept). They say having two implants will help, but I am not sure. Implant will improve her life, but it won't cure it. If she heard sounds she'll do well with implant with very little therapy (I didn't have any therapy after my implant). But she'll be making alot of trips for mapping (kind like tuning)
You should go to Cochlear - Implants for Children and Adults - Bionic Ear Hearing Implant | Cochlear Their implant is from Australia where you live so I'm surprise you are having trouble with it.
Again, sign up for SIGN LANGUAGE and try not to worry about making her hearing.
