Last time I was there ( about 4 years ago) photography was unrestricted. Apart from the main house and the 1930s shop/post office there wasn't a lot of real photographic interest. A great place with an astounding history- just not very photogenic.
Don't get me wrong. There are some picture possibilities, just not as much as you might think. One of the guides was actually there during the war and if she hasn't retired and you are lucky enough get her, she will really bring the place alive for you.
