You can apply to get her assessed, any person over the agent 18 can get someone assesses, bit hefty fines if it's done in a malaise way.
She will be held in a mental facility for three days in which time she will be assessed by a physc. and they will work things out from there.
I wish u the very best of luck, our mental health in Australia isn't At it's best, IMO.


Love me
That is only is their is clear and present evidence that the person in question may be considered a danger to themselves and/or to others, or with some other justifiable cause. Which honestly does not appear to be the case here. No Mental Health professional will do anything that will take away a persons liberty without sufficent cause and jepardize their career, their lisence to practice and even holds the possibility of huge fines and gaol time. It is NOT easy or even possible to have just anyone 'committed'. Once upon a time, this may have been more common place, but is not the case anymore.
