A number of smaller feasts, drill practices, weekend events, and tournaments are held throughout the year. These typically focus on the period dealt with by the group. Some historical groups are involved in ceremonial duties and teaching history. The Light Horse living history group and many 20th Century groups have associations with the Returned Services League (RSL) and are usually involved in ANZAC day duties. There has been a re-enactment of the Castle Hill convict rebellion (also known as the Battle of Vinegar Hill) and the Eureka Stockade, two historical battles of significance on Australian soil. The Australian Medieval Conference is a large biennial event focusing on arts, culture, and combat of this period.
