Affair exposed in Australia is ongoing (7)
I believe the answer is:
liaison
'affair' is the definition.
(I know that affair can be written as liaison)
'in australia is ongoing' is the wordplay.
'in' indicates a hidden word.
'LIAISON' can be found hidden inside 'australia is ongoing'.
'exposed' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for liaison that I've seen before include "Binding agent of a sauce; secret relationship" , "Amour; communication" , "A contact or affair" , "Cooperation between people or organisations" , "carryon" .)
