    Interesting bit of trivia, never heard that one before. Were these
cards official Apple products (with an xxx-xxxx-xx product label code)
or 3rd party manufactured specially for those sold in AU/NZ.

    Here in Canada we were given the same cards as in the United States,
but Apple Canada delayed several months before included them free with
systems (they also included MouseDesk with System 1.0 as the so-called
"System Disk" here, right up until about mid-1988).

    Yep, if you run older ProDOS 16 software (e.g. System 3.1) the newer
version of QuickDraw is read and used from ROM, so when you scroll windows
and move graphics around they are as quick as under System 5. I find that
a nice advantage when your forced to run ProDOS 16 (which of course was
so slow, you could actually take notice of it drawing to screen).
