I got ours fitted at Royal North Shore Hospital, my hospital gave me the details when I went for our classes, if you call North Shore Private hospital maternity or even RNS hospital maternity

the other option you have is to keep the carseat and hire a capsule until the baby can sit up forward facing and then use the current carseat you have purchased when the baby can sit upright unsupported and weighs the appropriate weight to sit forward facing.
Thanks Belle, those are great tips.

I will give our hospital a call or check when we attend the next class.

If the SnS Platinum doesn't fit, a capsule is will be for the first few months...
