Antipodean too in French and English (6)
I believe the answer is:
aussie
'antipodean' is the definition.
(I've seen this in another clue)
'too in french and english' is the wordplay.
'too in french' becomes 'aussi' ('too' in French).
'and' means one lot of letters go next to another.
'english' becomes 'E' (abbreviation).
'aussi'+'e'='AUSSIE'
(Other definitions for aussie that I've seen before include "Someone from Sydney? (slang)" , "Antipodean native, informally" , "Native of Canberra (colloq.)" , "Sheila from Sydney, perhaps?" , "Someone from Melbourne, perhaps (slang)" .)
