Kid close to Ayers Rock (5)

I believe the answer is:

sprog

I'm a little stuck... Click here to teach me more about this clue!

'kid' is the definition.
(I know that sprog is a type of kid)

I cannot understand how the rest of the clue works.

(Other definitions for sprog that I've seen before include "Baby (slang)" , "little one" , "Child, colloquially" , "Child; recruit (mil. slang)" , "Kid" .)

I've seen this clue in The Guardian.
