Winkalotts is awesome and as long as they have your item in stock, they ship to Aus in usuallly under a week.
The BJCS is a wonderful pram. The extras I got (not including second seat etc when next child came along) were the belly bar and the child tray. Both are excellent and Winkalotts should have them in stock or most baby stores have them too. I also bought seat liners online to make the seat/s a biut cosier. Tin Whistle and harmonyj have online stores and they make great liners to fit
It is so exciting waiting for a pram to arrive isnt it
