Something to do with Matilda in Australia (5)
I believe the answer is:
waltz
'australia' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for waltz that I've seen before include "Last dance?" , "Dance in 3/4 time" , "A flowing melody or dance in triple time" , "Valse" , "The 123, 123 ballroom dance" .)
