Indian state sport freak (2,3)

I believe the answer is:

go ape

'freak' is the definition.
(I've seen this in another clue)

'indian state sport' is the wordplay.
'indian state' becomes 'goa' (Goa is a state of India).
'sport' becomes 'PE' (short for Physical Education).
'goa'+'pe'='GO APE'

(Another definition for go ape that I've seen is " Throw a wobbly".)

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