I purchased a 17" catcher from riff.raff53 and had it couriered down to melbourne for about $120. I'm happy with it, fits well.
I purchased a green painted one which he sprays with hammertone, the colour's not really that similar to Scott Bonnar green and it scratches off pretty easily, I figure it'll rust before too long. Still, for the price I think it's a good buy and he sells unpainted ones slightly cheaper if you wanted to paint them yourself.
