Tima, I don't think you're understanding us. Chameleons NEED to eat insects, and preferably live insects. Chameleons actually will not recognize an insect as food unless it's moving around. Ocassionally you can get a chameleon to eat a little bit of fruit or veggies but they can't SURVIVE on a diet of veggies alone. It's like a tiger, tigers NEED meat to survive and would not do well eating apples and oranges for very long.
I'm sure you can get a hold of insects somewhere in SA, even if you have to go out and catch them yourself. But unfortunately, your chameleon will not be able to survive very long without insects.
