What is "shearers"

Usage examples of "shearers".

Still I see the shearers drinking at the township in the scrub, And the army praying nightly at the door of every pub, And the girls who flirt and giggle with the bushmen from the west -- But the memory of Sweeney overshadows all the rest.

Where the drovers and the shearers and the bushmen and the rest Never reach the Eldorado of the poets of the West.
