If you're currently flying a Kingair then I'd stick with that rather than chasing some pipe dream in Africa. The scene has changed a lot over there (according to mates who have friends there and who used to work there). If you're not already in the LHS, do your darndest to get yourself in that seat.
Jet jobs are a bitch to come by in Oz. Especially with QF being so shaky. A few mates are in Air New Zealand but they did have some jet experience (Falcons etc). Keep an eye out on what's happening in HK would be my advice.
