Others strangely not available around some water (5,3)
I believe the answer is:
north sea
'some water' is the definition.
(North Sea is an example)
'others strangely not available around' is the wordplay.
'strangely' is an anagram indicator.
'not available' becomes 'na' (abbreviation).
'around' is an insertion indicator.
'others' with letters rearranged gives 'orthse'.
'orthse' going into 'na' is 'NORTH SEA'.
(Other definitions for north sea that I've seen before include "Waters east of the UK" , "'It lies between Britain and Scandinavia (5,3)'" , "Expanse of water" , "Marine area off Britain" , "large body of water" .)
