With an aim to promote the advancement of agriculture, particularly relevant to the Western Districts of Victoria, the Hamilton Pastoral & Agricultural Society's activities encourage and celebrate excellence and innovation in agriculture.

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 The success of Sheepvention led to the exciting launch of the Beef Expo in 1992 and in 1995 the Spring Show was withdrawn from the list of events.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 two annual events with Sheepvention in August and the Beef Expo in February. In addition, the Society manages the hire of the Hamilton Showgrounds and Hamilton Exhibition and Conference Centre.

The Society is a member of Victorian Agricultural Shows Limited and the Association of Agricultural Field Days of Australasia.
