Caro , Jo, if you are interested, when I googled to find bulk nappy suppliers in sydney I came across one in WA called nappyonline. Its nappyonline with a dot com dot au. They have the Infant sizes in a box of 100 and they deliver the box to you. I just looked and its $38.09 plus 2.95 delivery in Perth. I dont know if thats any cheaper than buying them in the smaller packs, but just thought I'd let you know they are available in Perth!
