Every state in Australia has different legislation and processes etc. I know that in QLD there can just be one notification for action to be taken, but I believe in NSW there needs to be several reports before the matter is investigated. I know that it seems horrible to remove a newborn baby from his/ her parents, but on the other hand they are the most vulnerable and rely soley on their caregivers to ensure their care and protective needs. If the parents arent able to demonstrate an understanding of the concerns regarding the GF and cannot demonstrate their ability to prioritise their little one's safety by continuing to live with the GF, they are unlikely to be able to protect that child from harm...

Its hard to say without knowing all the facts!
