Obviously, I can only answer that question for me. With it being a very strong community-level celebration, I think different communities would have their own perspective on the event and on what was memorable.
From a national perspective, I think the two I would mention would be the New Dawn performance in central Australia and, second, the establishment of a rail link between Darwin and Adelaide, which had been a dream for most of Australia's history. I think that was a major visual from the centenary that most people would remember.
My suggestion would be that if you want to have a big impact on the country's consciousness, these big, highly visual events can certainly have a catalytic event across the country and can really increase the sense of nationhood. That was a big objective for us.
