Residents of Brisbane whinged once again? (4)
I believe the answer is:
anew
'once again?' is the definition.
(I've seen this in another clue)
'residents of brisbane whinged' is the wordplay.
'residents of' indicates the answer is hidden within the clue (I've seen 'resident of' mean this).
'ANEW' can be found hidden inside 'brisbane whinged'.
(Other definitions for anew that I've seen before include "Again but differently" , "Wane in a different way, again" , "From the beginning again" , "Once more (poetic)" , "Afresh" .)
