Just a few corrections to Von Smallhausen's post:
6. What is the full name of the South African Currency?
It's actually just the South African Rand. The Krugar Rand is legal tender in SA but isn't actually a currency, it's more a status symbol for gold investors.
15. Which native bird is the heaviest in South Africa?
Although I've never heard of the Kori Bustard, I would say that the heaviest bird in SA is the Ostrich, since they are a native bird found in almost all parts of the country, are certainly the tallest and can weigh more than an average man.
Edit: Visage has already posted a few of the things I've said here but I'm gonna leave this post anyway, can't be bothered to edit it
