Assisted passage of young people on the continent by the sound of it (10)

'assisted passage' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'young people on the continent by the sound of it' is the wordplay.
I cannot quite see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
'continent' could be 'asia' (Asia is an example) and 'asia' is present in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

'of' is the link.

Can you help me to learn more?
