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

'gassandoil development' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'bass strait's part' is the wordplay.
I cannot quite understand how this works, but
'bass' could be 'b' (musical abbreviation) and 'b' is present in the answer.
'part' could be 'island' (I have seen 'Part of archipelago ' mean 'island' so perhaps 'part' could also mean 'island') and 'island' is located in the answer.
This explanation may well be incorrect...

'in' is the link.

Can you help me to learn more?
