Jumbuck's noise heard in watering hole (3)
I believe the answer is:
bar
'watering hole' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bar that I've seen before include "Prevent; sandbank" , "Length of wood or metal - drinking place" , "Ingot" , "Barrier; pressure unit" , "Ballet dancer's exercise rail" .)
