Nah, don't be sorry Raul, New Zealand is pretty much just a suburb of Oz anyway, and we've been propping up NZ's "third world" economy for many years in the form of welfare payments to about half of NZ's population who have moved over here to seek a better life. We love our Kiwi's like Americans love their Mexicans...........
Now back to your question, yeah, we've had a few goes at developing our own motorcycle industry, but due to our relatively small population and the fact that we're so far away from the rest of the world, (apart from bloody New Zealand, of course.........) we haven't had much luck, except with some "specials" with small production numbers, quite out of my price range, sadly.
Mike Rieck's mate has an Aussie bike, a V8 Drysdale, which is pretty cool, but made in relatively low numbers. Listen to what it sounds like, it sounds like no V8 I've ever driven, ha ha!

Now the designer/builder is a South African guy who emigrated to Oz a few years ago, and the drive train is American, but just like Harley is at least "technically" an American built bike, the Barbarian is as Aussie as getting drunk and making a dick of yourself, ha ha!:
