Introduction of koalas in gums around lake in African city (6)

I believe the answer is:

kigali

'african city' is the definition.
(capital of Rwanda)

'introduction of koalas in gums around lake in' is the wordplay.
'introduction of' says to take the initial letters.
The initial letters of 'koalas in gums around lake in' is 'KIGALI'.

(Other definitions for kigali that I've seen before include "Rwandan capital" , "Capital of Rwanda" , "African capital" .)

I've seen this clue in the Sydney Morning Herald.
