From what I understand the NSW laws were going to be the same as of Jan 2009, but nothing ever came out about it. Maybe they are changing it to Jan 2010 ?????

Z is still in the built in harness too (only 16.5kg at nearly 5yo!). Cookiemonster, when you clean the Maxi Rider, underneath the foam padding in the seat there is a little compartment where the extra harness attachement is stored. When you get that out you store the regular one in there as well.
