I'm sorry to hear of your situation but, the like Ina, I'm not quite sure what this has to do with cross breeding of your dogs
Also, if you were intending to breed, why didn't you import a breeding pair - surely it would have been just as easy to import 2 as 1 purebred dog?
Alas, it sounds like the situation (and mentality of many) in Oz is just like that in the UK
