Is about to host a remote expedition (6)
I believe the answer is:
safari
'expedition' is the definition.
(I know that safari is a type of expedition)
'is about to host a remote' is the wordplay.
'about' indicates anagramming the letters.
'to host' is an insertion indicator (inserted letters are hosted or welcomed).
'a remote' becomes 'afar' (I've seen this before).
'is' with letters rearranged gives 'si'.
'si' placed around 'afar' is 'SAFARI'.
(Other definitions for safari that I've seen before include "Overland journey to look for wild animals" , "African hunting expedition" , "Big game trip" , "Hunting expedition (in Africa)" , "Hunting trip" .)
