True leaders of Australia can teach us about love (6)
I believe the answer is:
actual
'true' is the definition.
(similar in meaning)
'leaders of australia can teach us about love' is the wordplay.
'leaders of' indicates taking the first letters.
The initial letters of 'australia can teach us about love' is 'ACTUAL'.
(Other definitions for actual that I've seen before include "Existing in fact, current" , "Real and current (6)" , "Really existing" , "Real - true" , "Existing in reality" .)
