The push for smarter farming is at the core of Australia's tough agricultural history. Richard and Clarence Smith quarrelled over who was the true inventor, but their stump-jump plough improved the economic prospects of farmers working difficult terrain. Frederic Wolseley's mechanical shears eventually won over the shearers and transformed the wool industry. Lew Bandt designed the ute for farmers needing a comfortable working vehicle, and Benjamin Dunkerley invented a fur-cutting machine that led to the iconic Akubra.
