No shortage of Information about them it seems.

I think, maybe the Australian connection you maybe led to to them.
Just a guess... But aren't they from there actually? Cockatoos are.
I guess the best bet would be to obtain a weaned baby from a breeder, but I have no idea really.
Soooooo cute. All my childhood memories were quite good. (dangerously tempted for some reason...)
Big responsibility though.
For your stereo, you have an Alpine, it is an aftermarket upgrade for this car, (The Becker Mexico was the original, and it was crap) they are pretty good, so just play with the thing, program your favorite stations, set its clock, and learn how it works, AFTER the motor is warmed up, and idling in your garage space, (they can idle an hour and it won't hurt them...)
With any luck, there should be an owners manual for the Stereo (It is aftermarket, but if not, you are out of luck, because they are obsolete within weeks after they are new, there are better models coming out all the time)
I mention this because I also have an Alpine single CD no cassette player in mine and it is OK, but with a lot of fiddly and fussy gadgets on it I don't need. The worst mistake possible - I was in a hurry, and bought one to go on a trip with, and I didn't have the features I wanted, and have never been to happy with it.
But, Alpine has been known to be an excellent brand, so stick with it for awhile.
Back in the mid 1980's the Nakamichi was the "hot" set up for the gray market Euro cars. There was no such thing as CD players back then.
It wouldn't surprise me if your unit was installed around 15 years ago, give or take. It was probably obsolete 3 weeks after it was removed from the box.
But upper end equipment, nevertheless
Good nite/CS
