Can't see anyone providing the answer to the original question on here (unless I've missed it), but XG518 was with 208 Sqn at Bahrein for this period.
Then it must have been detached from Aden to cover an 8 sqn or 208 sqn detachment at Muharraq. BTW 208 were based in Nairobi at that time. I escorted an Aden based Sycamore from Um Said (Qatar) to Bahrain with a Pembroke (SAR cover for a Rhodesian Air Force Sqn Venom detachment from Aden) on 8/2/60. 208 sqn (Hunters) wasn't stationed in Bahrain until 1964 by which time the Sycamores had been replaced in the middle east. On the other hand that landscape does not look like anywhere in the Gulf, but it does remind me of parts of Kenya.
I was flown to the Jufair Jetty in the (yellow) Sycamore after being winched from the sea during a dinghy drill, but didn't record the serial number in my log book.
