i'm currently reading r m w dixon's book australias original languages, and find it an excellent read!
i would also recomand bruce pascoe's black emu book.
i often state, that in reality things often are 180 degree, the opposite from what the collective mind suggests.
for example : street drugs are more dangerous than prescription drugs.
or the best way to regulate a water way is by a straight line and reinforced banks.
i just start to understand, that indegious languages are, very sophisticated, and extreemly precise,
and even feature a different form of speaking, if the mother in law is in hearing distance, as a means of respect.
it was always my dream to learn a native language, but my library search revealed no sources.
there is "audio" for every language of this world but none of the country, most of us live in.
this is a shame!
