I had a two share room with DS in public system. I did get stuck with one lady who's partner was horribly abusive and degrading. We complained to the middies about his language and they moved her after a day or perhaps she was discharged- not sure
After that the next lady was lovely. No issues at all. We were both fairly considerate etc. I spent 5days in hospital after a Csection.
If you have a natural complication free delivery and healthy bubs the public system in qld likes you to spend as little time as possible in the ward. Usually. 1-2days. It's alot shorter than it used to be. But I actually would prefer to be home sooner and not have to share rooms etc.
