I'm also Aussie, so talking in Aussie dollars. I can't really give you an actual figure (I don't even want to know haha!), but here's what I've learned.
I never thought to get a pram that you can build on (for toddler and newborn), so went with what I loved/trendiest, which was the Bugaboo Bee - $1200. While I adore the Bee, we are now expecting our second, and need a new pram! (Granted, the Bee was a gift, but still!)
As a newborn, our bub was wetting through nappies, and some days we were going through 3 to 4 changes of clothes. Don't underestimate how many singlets and onesies you'll need! If you can, don't take tags off clothes until you are ready to use them. They may only be in 0000 clothes for a short amount of time, and even Bonds stuff is pretty expensive these days.
Footless onesies may last you a bit longer than the ones with feet in.
Don't buy a breast pump until you are sure you can breast feed (not being negative, I just know so many women that wanted to but it wasn't for them). Again, I was given a brand new one which went unused (I breast fed for 9 months but didn't have the need to use a pump, and was happy to use formula on the odd occasion I wasn't around).
Everyone told me to get a 'Milk Bar' (a breast feeding pillow) but I wanted to wait and see, and I'm glad I didn't. A cushion sufficed in the beginning and then I didn't need anything as we got faster and more comfortable.
I had Billy at a private hospital in Brisbane with an obstetrician (and private health insurance). For a 5 day stay in a private room with my husband, I *think* we were out of pocket about $1000.
Our babybjorn was an absoloute godsend and living in Tokyo, I could not have done without it, however our son is a tall, solid lad and became too heavy for me to carry much earlier than normal. I think it would have been a different story if I had an Ergo (option to carry on the back) so am probably going to get on of those for our second.
We splashed out with our high chair and got the Stokke Tripp Trapp (about $350), but it's well worth it. Not necessary til 5 - 6 months though.
We went without a change table (no space in Japanese apartments!), and just used a change table mat on a bed/floor/wherever, so I don't see them as a necessity though I'm sure many would disagree.
It's hard with your first as you want everything to be perfect, so I decorated the nursery beautifully with expensive, good quality Kaloo and perfect matching colours. Of course, he never used/noticed any of it, and I would have rather saved the money to decorate his 'big boys' room which he appreciates now!
The babybjorn bouncer we bought was also well worth the money.
Sorry, this is been quite all over the place... you'll have to excuse my random thoughts. I hope it has been of some help! Good luck
