Moving to Gibraltar from the UK?

Im thinking about moving to Gibraltar in the next couple of years. Im 29, and retired from the Army due to injury. At the moment Im receiving a war pension an Incapacity Benefits, and Disability Living Allowance with the amount relating to my injury. My question is, because Gibraltar is a British Overseas Territory, would I still be entitled to my benefits, and declare them as a source of income? I'd phone the DWP, but they'd assume Im moving right now, as opposed to thinking about it.
