If you are looking to convert to fly ZS aircraft , you are looking at the worst time for low time pilots in many years , actually for pilots as a whole . The airlines have almost stoped hiring and as a result GA is full
However if you are looking at botswana and Namibia , the conversion process is much simpilar , especialy in Bots where quite a few Aussie pilots fly.So i would recomend Bots.
Not that there is much work there either but at least its a better piont of contact and easier to convert
