Aussie native taking tea with male fellow lodger (4-4)
I believe the answer is:
room-mate
'fellow lodger' is the definition.
(I've seen this before)
'aussie native taking tea with male' is the wordplay.
'aussie native' becomes 'roo' (I've seen this in other clues).
'taking' is a charade indicator (letters next to each other).
'tea' becomes 'mate' (South American hot drink).
'with' says to put letters next to each other.
'male' becomes 'm' (common abbreviation).
'mate' after 'm' is 'mmate'.
'roo'+'mmate' is 'ROOM-MATE'.
(Other definitions for room-mate that I've seen before include "One sharing accommodation" , "Fellow lodger" .)
