Supporter died here in a part of Australia (8)
I believe the answer is:
adherent
'supporter' is the definition.
(I've seen this before)
'died here in a part of australia' is the wordplay.
'died' becomes 'd' (abbreviation next to the year of someone's death).
'in' means one lot of letters goes inside another.
'a part of australia' becomes 'ant' (I can't explain this - if you can you should believe this answer much more).
'd'+'here'='dhere'
'dhere' put within 'ant' is 'ADHERENT'.
Can you help me to learn more?
(Other definitions for adherent that I've seen before include "Disciple, follower" , "Devotee" , "Weep" , "Supporter, follower" , "One supporting" .)
