Zane ends in North Bass Strait island summerhouse (6)
I believe the answer is:
gazebo
'summerhouse' is the definition.
(I know that summerhouse can be written as gazebo)
'zane ends in north bass strait island' is the wordplay.
'ends' means to remove the middle letters.
'in' means one lot of letters goes inside another.
'north bass strait island' becomes 'Gabo' (Australian island in Bass Strait).
'zane' with its middle taken out is 'ze'.
'ze' put within 'gabo' is 'GAZEBO'.
(Other definitions for gazebo that I've seen before include "Small summerhouse or open hut" , "Summerhouse with a good view" , "Summer house with a wide view" , "Small summerhouse for shade" , "Type of summerhouse" .)
