That's the code for Australia, and Asia other than China or Japan
I don't know if anyone's yet tried making a warranty claim at Fuji UK on a body with a non-EU code (UK should be N). With that gamble in mind, I think I'd still opt to save the extra cash buying from OSD who I've used in the past - unless the refurb store come back with more at £270. If I'm getting an unofficial import I'd rather buy from a seller that's open about it up front. UKCS don't even put the price on the main page until you initiate an order.
