Hats block Austrailia that is linked to hat academy sells exactly what you are looking for I think.
I am NOT in Australia...but I would love to see my heads wearing your hats...they make my heads smile (if they could). Take a peek at www.crunkleton.com ... I do have 22 different heads, all beautiful, I would even give some discount on the shipping from USA to Australia. Mainly because I love your pretties....they make my heads look even better.
