Dear Terry

Thanks for the detailed response.  Wikipedia is marvellous.  I have a
vague memory that indigenous Australians used arrows when hunting, but
I'll have to check on that.  I'm more sure that they used (and still
use) boomerangs to knock out an animal, and also the "waddy" or "nulla
nulla":

"The Nulla Nulla is one of the most deadly weapons, whether used at
close quarters or thrown.  The shape may vary between tribes but is
usually between half to one metre in length and can be used as a club or
throwing stick.  The handle tapers to a sharp point near the handgrip,
towards the other end the handle widens into a bulb.  Like the
Boomerang, a Nulla Nulla could light a fire using the same method of
spinning it quickly with downward pressure in the surface crack of a dry
log and a spark was made. Nulla Nulla was basically a throwing stick."

They would not, however, use a "Bullroarer" as a hunting device; not
even Sometimes.  Such a "Golden Age" never existed.
