I think AvGen are at the forefront of importing new breeds into Australia. I was wanting some White Siciliana utility chickens or some Bresse utlility. Although they only sell bresse under contract.
I think it will be a while till they establish numbers and make their money back from the 2014-2016 imports, they have a website with them.
Hoping these breeds are released more widely and become cheaper, as i read other posts showing trios sold for $700 - $1000 a couple years back.
