Colony on strike mail (7)

Ross

I believe the answer is:

outpost

'colony' is the definition.
(I know that outpost is a type of colony)

'on strike mail' is the wordplay.
'on strike' becomes 'out' (I've seen this before).
'mail' becomes 'post' (synonyms).
'out'+'post'='OUTPOST'

(Other definitions for outpost that I've seen before include "Remote part of an empire" , "Distant part (of empire)" , "Remote military site" , "Remote settlement" , "isolated settlement" .)

I've seen this clue in the Sydney Morning Herald.
