"For most people, the words of ‘Waltzing Matilda’ embody the free spirit, resourcefulness and defiance of authority associated with the Australian national character... Some scholars and folklorists argue that the song is a political statement in much the same way as classic children’s nursery rhymes attacked political figures in earlier centuries. The song is not an explicit attack on the squatters’ refusal to pay shearers higher wages. However, it has been argued that the plot of (the song) ‘Waltzing Matilda’ is based on the conflict that raged between these two groups in the 1890s before the song was composed."
