My desire for Australian port (7)

I believe the answer is:

geelong

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

'australian port' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'my desire' is the wordplay.
'my' becomes 'gee' (I've seen this before).
'desire' becomes 'long' (longing is a kind of desiring).
'gee'+'long'='GEELONG'

'for' is the link.

Can you help me to learn more?

I've seen this clue in The Independent.
