This particular area of S.A. is over by Durban (eastern coast). I suspect even if they opened it up to whites...you wouldn’t find that many interested in the region (extremely high crime rate). The other issue is that they will end paying those who apply....a lesser wage.
I spent two weeks there this past fall. There’s tons of opportunity and potential...but the government is so corrupted and the public so skeptical of intentions...that it can only fail. I had two or three black African comment that they need a Trump-like figure to arrive and just motivate change.
The change agent they are going to get is going to be very ugly.
