Originating in the 1200's. Family Crest from the Line of Philip de Mowbray(Philip de Mowbray I of Barnbougle, Dalmeny and Inverkeithing), Scotland.
I personally feel that Barnbougle Dunes should define itself with Tasmanian or even Aboriginal art. Tasmania has been living with a strange history, one developed between dreams of a British past, the present ideas from America, and a search for its own positive identity. Evolving an image away from its penal colony beginnings, Barnbougle will be a nice addition for that cause. A respectful logo wouldn't hurt.
I don't hate the one used now but the place could use a larger statement. With an interesting but odd name like Barnbougle Dunes, I think the name itself should be prominent - perhaps in an Engravers font and with Tasmania as largely displayed as well. It's funny how I tell people that I'd like to travel next to Tasmania, they always look bewildered and say something like "Wow, Sounds cool. Why Tasmania? Where's Tasmania? What's in Tasmania?" What's funny about it is they are always intrigued by the answer of golf (?). I'm not one to go to a foreign country just to play golf though, the country itself sounds very mysterious and wild.
I like the seahorse idea as a motif as they are a big part of the region. I think they even have some kind of seahorse aquarium/museum/expo in Launceston.
There's a terrific book written by a Tasmanian feller named Peter Conrad called "Behind the Mountain - Return to Tasmania" and it has some interesting insights into the history, culture and prospects of the little island.
