Apart from getting the validation as well, i'm pretty sure to qualify for the job , you'll have to get a South African Permanent Residence permit.... unfortunately i don't know how strict the authorities are on this matter. I say this, as i had the same hassle a while back trying to get into an airline that was recruiting.
I don't know what your situation is but give it a thought as they don't mention these things sometimes to the foreign guys.
Good luck anyways.
