Pick up a JP fleet guide and look at Botswana, S Africa, Kenya, Namibia. There are numerous employers flying single piston Cessna's into the Okavanga Delta. Sefofane and Delta would be a couple of the bigger ones, but you'd better pack a bag.

Solenta out of S Africa will hire none S Africans for various operations across the continent, including UN and Red Cross, as well as DHL (caravans, B1900's, ATR42's). They may want some time in the bush there.

PNG, or Papau New Guinee is where many Antipodean newbies end up; again, the JP Fleet guide should steer you in the right direction.

If you lady is an ESL person then Japan would be great, but you'd need the time. Somebody mentioned the Chinese domestic schools (perhaps in Zuhai?), and that might work. Some camps in Africa would hire her as well, but not to teach English, more cook/chamber maid thing.

Good luck and have fun.
