I believe the answer is:

airfreight

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

'cargo' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'i fear right sort' is the wordplay.
'sort' is an anagram indicator.
'i'+'fear'+'right'='ifearright'
'ifearright' is an anagram of 'AIRFREIGHT'.

'of' is the link.

Can you help me to learn more?

(Another definition for airfreight that I've seen is " carriage".)

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