As a general guide, partners are usually only allowed to stay in private hospitals. Accomodation for them can be anything from a double bed shared with you, to a fold out recliner or sofa bed depending on the hospital.

Many private hospitals provide meals for partners but they are charged for them - usually something around $10 per meal. Partners aren't usually "officially" permitted to use the shower but some hospitals may turn a blind eye if you're not sharing the bathroom with anyone else.

Public hospitals pretty much never supply food for dads, and they aren't allowed to use bathroom facilities because these are usually shared with other mums. They are sometimes allowed to stay if you aren't in a room sharing with someone else.

None of this is to say that private hospitals are necessarily a better choice though - public hospitals have lower rates of intervention and caesarean and usually more supportive of breastfeeding so if those things are a priority for you a public hospital is still a better option. After all your postnatal stay is only a few days. The birth stays with you forever
