Where there's division, there's conflict.

Ordered by number of conflicts, in decreasing amount:

Tribes > Nation-states > Unions.

There will be more wars when the European Union breaks up. Or when the US does.

Conversely, Africa will greatly benefit from becoming more united in the same way the West has. This is now being reverted (see Trump, Brexit), so you just wait and see where that takes us.

There are thousands of tribes in Australia. Where is their civil war?

It isn't as simple as you say, because a tribe is more than you seem to think it is. I can change my country, I cannot change my tribe.

Having many tribes does not mean unity is impossible.

"The Australian Bureau of Statistics estimated the total resident Indigenous population to be 458,520 in June 2001 (2.4% of Australia's total)"[0]

You're missing my point. There are no tribes in Australia, for practical purposes. Australia has moved past the concept of tribes. In Australia, people are born into Australia.

In Africa, in 2017, people are born into a tribe.

That is utter, utter crap.

The Tiwi don't associate with the Kimberly kids. Their islands are closed to outsiders. You are given your totem at age of 12 in a smoking ceremony that outsiders are not permitted to witness. You are not born Australian. You cannot marry one. You are Tiwi.
