true grit...
As mentioned, the War Memorial has an impressive collection. From tiny personal relics to massive examples of pre-computer engineering skill, it gives you a real look into what things were actually like. I probably learnt more about World War I and II in those few hours than I ever learnt at school - certainly a more memorable exposé.
While I found that the smaller exhibits had more impact for me than the larger exhibits like the tank above, I've always had an affinity for the utilitarian aesthetics of war machines. There is a distinct stylistic consistency present despite each object being unique in operation, design and purpose, which is fascinating to me. Maybe it's the result of a specific level of technological development, or perhaps just a mirror of design values of the time.
