What is the least worst emergency department mental health ward?

UPDATE: Shit, you guys! This really blew up! Thank you for all your advice; I've formed a solid plan and feel ready to advocate for my friend tomorrow.

My friend is in serious mental illness crisis, to the degree that urgent care isn't suitable.

I know Joondalup Health Campus is a pretty nice hospital, as hospitals go, and that Royal Perth Hospital is generally dilapidated. I assume Murdoch and Fiona Stanley would be nicer, given they're newer facilities.

My question is: what is the least uncomfortable psychiatric admissions department? I assume you'd spend a few days in the ED part before being moved to a ward.

Please DM me if you'd rather not comment in the public forum.
