Hi Tulip, I'll have had 3 different hospitals for my 5 births, two public on private. You need to ask for a list from the hospital of what you need to bring. They should have provided you with this when you booked in or went on a tour. All the hospitals that I have used provided everything from wipes and nappies, cloth and disposable, baby clothes, wraps, booties/socks and little beanies., I just had to provide my own personals and clothes and clothing and nappies to take baby home in.

The Mackay Mater Motel... I mean hospital lol, is the best (It is private, so we do pay for it, lol, not out of pocket though.) they provide everything for baby including bags of huggies nappies and packs of J&J baby wipes, powder and soap. Their clothes and wraps are really cute and they match, believe me that is amazing. On your arrival you fill out what you want on your last night in hospital (need to give them some indication as to when) They provide you with either Strawberries and cream with champayne for 2 or cheese and wine platter for 2 and they will take bubby to the nursery so you can be alone for the evening. When I had DD#4 it coincided with the town Christmas Carols, my room overlooked the River so we had a romantic feast with fireworks on the water, can't get much more romantic than that lol. I didn't have the champayne, infact I gave it to my sister, I didn't feel like it. Although all the research suggests that having a glass of bubbly/wine or beer will not cause any harm and infact can be good for milk production. I certainly wouldn't consider having any spirits, they are definately a no no.
Other things I bought
latest mags, (hospital provided the paper daily)
my own wheat hot pack- essential
nice personal products eg shampoo/conditioner, soap, deoderant, maternity pads atleast 3 packs depends on how long you intend to stay and breast pads

Ural (urinary alkalizers) although hospital provided this - essential for the first 24 hours makes wee less stingy, definately take some they really help, I've never torn but everything certainly gets stretched to the max lol.

And a note of advice lol (warning TMI if you proceed)
Your insides will not fall out when you go to do your first no.2 after birth, might seem like a silly thing to say but just wait and remember lol.
