Disinclined to write that India's poised to expel Australian industry leaders (10)
I believe the answer is:
indisposed
'disinclined' is the definition.
('indispose' can be a synonym of 'disincline')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for indisposed that I've seen before include "Out of sorts" , "Poorly" , "Slightly unwell" .)
