@WillyI'm so sorry to hear about your frustrations in terms of trying to speak out about the mistreatment of people with serious mental health issues. I can relate, as I've often spoken out about mental health treatment and much of the time, it felt like nobody wanted to listen (and on many occasions, it felt like the powers that be wanted to bury my testimony altogether).
I'm not sure if your aware, but there are numerous organizations out there that seek to give a voice to the "mentally ill", and many take a special interest in bolstering the voices of those who have been harmed by the mental health system or other carers/helpers.
There's VMIAC (for VIC), Being (NSW), and LELAN (SA), just to name a few. There's one for WA, too, (the name of which escapes me at the moment 🤔), and I hear tell that there's a comparable fledgling organization in QLD finding it's legs.
On the fedral level, there's the National Mental Health Commission, which is taking a refreshing new interest in drawing "Lived Experiance" input into all their future policymaking. In practice, this means that there will be frequent open public consultations, to allow regular "Lived Experiance" people to throw their own 2 cents into all future policy development.
There's also "Lived Experiance Australia", which is an advocacy organization which seems to be closely affiliated with SANE. My understanding is that, if you have a gripe you want to air about mental healthcare, you can send them an email about it, and they may factor that into their future advocacy in government consultations.
And also, since your particular interest seems to be "serious psychotic illness like bipolar disorder and schizophrenia", that probably classifies as a disability; which means you can air your grievances to the Royal Inquiry into the Abuse of Disabled People.
