a drop in the ocean

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

'overseas parachutist?' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'little bit like an' is the wordplay.
I cannot quite understand how this works, but
'bit' could be 'drop' (I have seen 'Bit of water' mean 'drop' so perhaps 'bit' could also mean 'drop') and 'drop' is found in the answer.
'an' could be 'i' (Roman numeral for one) and 'i' is found within the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for a drop in the ocean that I've seen before include "Drink for a drifter" , "Certainly no effect of global warming" , "something insignificant" , "almost nothing" , "barely noticeable" .)

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