The impact in a concrete sense was, as I mentioned, the railways and some of the concrete projects that were built during the centenary or constructed at the time of the centenary. They were, if you like, tangible results from the year.
I'll leave it to others to make the case as to whether some of the intangibles have helped knit our national fabric together more tightly. There was certainly a great sense of pride in Australia at the time of the centenary. Australia being the country it is, some of that has of course evaporated in the time since, but I think people did take from the year a great sense of national pride and an improved understanding of our history as a country.
