Aussie jumper’s time to get somewhere to sleep (5)
I believe the answer is:
roost
'somewhere to sleep' is the definition.
(I've seen this before)
'aussie jumper's time' is the wordplay.
'aussie jumper' becomes 'roos' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'time' becomes 't'.
'roos'+'t'='ROOST'
'to get' is the link.
Can you help me to learn more?
(Other definitions for roost that I've seen before include "Thin paper" , "Rest on a perch" , "In Orkney, the current" , "Settle down (on a branch?)" , "Hen's resting place" .)
