Aluminium leaving here for a place in Europe (7)

I believe the answer is:

austria

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

'in europe' is the definition.
('Austria' is part of 'europe')

I don't understand how the remainder of the clue works.

(Other definitions for austria that I've seen before include "Republic of central Europe" , "part of Europe" , "German-speaking republic" , "land in Europe" , "Central European republic" .)

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