OK this may not be for everyone, but I found it very interesting, and beautiful and stunning. It is free, you get free guided tours and they had some amazing art works on display. The cabinet wasn't sitting when we were there but apparently anyone can go in and watch.. now that would have been interesting. They also have a great cafe with reasonable prices. The scenery is beautiful, looking down from Parliament house down through to old Parliament house and then the War memorial. I undertsand this is not everyone's cup of tea, and the younger kids were bored, but I enjoyed it.

Approximate cost: $free
