Six balls left with run between Brisbane and Perth? (8)
I believe the answer is:
overland
'run between brisbane and perth?' is the definition.
(to overland is to travel a long distance on lan)
'six balls left with' is the wordplay.
'six balls' becomes 'over' (cricket).
'left' becomes 'l' (common abbreviation).
'with' becomes 'and'.
'over'+'l'+'and'='OVERLAND'
(Other definitions for overland that I've seen before include "Cross-country" , "Lover Dan (anag.)" , "Not by water or air" , "By road or rail" , "By a route not involving sea or air travel" .)
