It's a novel about worker from area in Australia (8)
I believe the answer is:
tasmania
'in australia' is the definition.
('Tasmania' is part of 'australia')
'it's a novel about worker from area' is the wordplay.
'novel' indicates anagramming the letters.
'about worker' becomes 'mani' (I am not sure about this - if you are sure you should believe this answer much more).
'from' says to put letters next to each other.
'area' becomes 'a' (maths abbreviation).
'ts'+'a'='tsa'
'tsa' with letters rearranged gives 'tas'.
'tas'+'mani'+'a'='TASMANIA'
Can you help me to learn more?
(Other definitions for tasmania that I've seen before include "Asian ATM in Australian federation" , "State off 23 [VICTORIA]" , "Pacific isle" , "Pacific island" , "somewhere in Antipodes?" .)
