From memory, the exhibit is only a little bit bigger than the photo shows and only the front metre-metre and half, is uncovered.
I didn't think this was a very impressive exhibit and all the metal in the background wrecked the 'immersion' feel that had been brilliantly applied to the rest of the park.
The Townsville breeding program was ceased and the group split up between the two collections, one in the deep south of Queensland and the other one in the far north of the state. I visited Port Douglas in 2007 but only found out what the other collection was upon arriving back in Iceland.
