G'day Felix,
I did bush flying (well, a version of it) for a few years in Australia. (Australian citizen - as well as British - with an Australian CPL etc). Amazing experience and it is useful time. During my command upgrade on a jet, I did use that experience to effect good outcomes.
You won't regret it so long as you maintain good discipline and standards.
To search for suitable operators in Africa, look up scenic flights over waterfalls etc. That's a safe start. That'll give you an insight into Africa flying and whether or not you want to continue.
Always keep an eye on the future. ie, twin time, turbine time, instrument time etc. Be prepared to walk away from a bad deal. Better to be broke than dead.
Your log book will become a diary. A diary filled with incredible memories and experiences. You've got the rest of your life to sit in a jet with the autopilot on.
