Hey Yep I am in WA! Heh heh. How annoying! Here's hoping you do win the auction. I actually thought someone would snap it up at $80 as there were a couple others listed for more than that.

Just did a quick measurement - the strap is adjustable and I estimate it will fit across a pram handle up to about 55cm wide. That's a rough guess though so if you like I can check it on my pram tomorrow (pram is in the car boot at the moment!) and give you a better idea.
