If Timatic doesn't say VOA is available then I personally wouldn't try it from distant locations, going with an overnight in JNB en route would be a far less risky way.
I know the OP was talking about going via JNB, but there was another poster (Leo123) who talked about arriving on QR and attempting to go back out on the same plane. Their experiences could be quite different.

I flew in and out of JNB to various other African countries and was never asked for evidence of a return ticket or any other kind of due diligence.
Once, in NRT, the bag drop agent didn't really have a concept of the European Union and started asking for evidence of onward travel even though I was an EU citizen terminating in AMS. It's always best to make life as easy as possible for yourself when dealing with airlines who might not know the processes as well as they should.
