Australian jumper, male, finds space (4)
I believe the answer is:
room
'space' is the definition.
(room is a kind of space)
'australian jumper male' is the wordplay.
'australian jumper' becomes 'roo' (I've seen this before).
'male' becomes 'm' (common abbreviation).
'roo'+'m'='ROOM'
'finds' is the link.
(Other definitions for room that I've seen before include "Space; chamber" , "Enclosed indoor space" , "Scope; living space" , "kitchen?" , "Space within a building" .)
