The Shearers Strike is acknowledged as the starting point of political and social processes, which led to the election of the first Labour representative to government anywhere in the world, and to the eventual formation of the Australian Labor Party.

The Tree of Knowledge is significant to the nation, in particular the Trade Union Movement because of the place's special association with the Shearers Strike of 1891.

Labour Day in Queensland is celebrated annually in the first week in May, coinciding with the march of shearers and bush workers on 1 May 1891, May Day, during the Shearers Strike.
