Since 1858, the Society held a Spring Show almost every year.
1952 saw the introduction of the Sheep Show which was then expanded and born into Sheepvention in 1978.
The success of Sheepvention led to the exciting launch of the Beef Expo in 1992 and in 1995 the Spring Show was withdrawn from the list of events.Today, The Hamilton Pastoral & Agricultural Society continues to hold the annual event Sheepvention in August.
