You could always try Zim first. They're not too keen on those with no right of abode but you may do fine following the 'tieing of the knot' ceremony. Failing that, take a ride up to Dar-es-salaam and Zanzibar then up to Wilson Airport Nairobi - time and finances permitting. Lots of hanging around required when job hunting away from home however. I'd strongly recommend you stake out the home base first (Zim that is) - must be something there to get you started and it sure as hell beats Arnhem Land in a sweaty 206.
Best of luck
