How is everything going for you?
I was looking at the site of the Office of Public Advocate and I think it’s worth you applying or talking to them there and seeing what advice they give you. I think you will find that your circumstances dictate you have a great need to ‘oversee’ your child’s affairs. Here’s the site in case you haven’t been there, which you probably have. https://www.publicadvocate.vic.gov.au/guardianship-administration/guardianship
I was wondering whether giving you power of attorney might be a way around all this – you can intervene or have a say. Not sure as I don’t know enough.
Anyway, hope all is well with you and yours. Cheers Bronnie 🙂
