Aussie gal (6)
I believe the answer is:
sheila
'aussie gal' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sheila that I've seen before include "Australian girl or woman" , "bird?" , "Girl's name; Six down (anag.)" , "Aussie lady?" , "Informally, a girl or woman in Australia" .)
