There isn't a significant African/african American community in terms of quantities in Australia at least until very recently (majority of the African migrants came here in the 2000's due to the Somalia wars)
While American culture that are popular do get filtered down here and yes that means we are exposed to Sly Stone and Stevie Wonder (I mean I have heard everyday people and superstition long before I even listened to any of their albums) they are not worship and mostly known for a few hit singles
The works from America that is going to appeal down here are more likely stuff that white people like.
