Country area repeatedly restricting deviant rituals (9)
I believe the answer is:
australia
'country' is the definition.
(Australia is an example)
'area repeatedly restricting deviant rituals' is the wordplay.
'area' becomes 'a' (maths abbreviation).
'repeatedly' indicates the doubling of some letters.
'restricting' is an insertion indicator.
'deviant' indicates anagramming the letters.
'a' doubled is 'aa'.
'rituals' with letters rearranged gives 'ustrali'.
'aa' enclosing 'ustrali' is 'AUSTRALIA'.
(Other definitions for australia that I've seen before include "Island continent" , "Commonwealth member" , "A US lariat can be found in this country, strangely" , "Commonwealth country" , "Barry Humphries' birthplace" .)
