Members of the Society for Creative Anachronism (SCA) fighting in a tournament known as 'the College Challenge.' The battle depicted in these images was fought between members from both St. Basil (UWA) and St. Lazarus (Murdoch).

About the Society for Creative Anachronism and the Kingdom of Lochac (the Australian and New Zealand regional branch of the SCA):
The Society for Creative Anachronism is an international organisation which focuses on the study and 're-creation' of Medieval and Early Modern cultures and their histories before the seventeenth century. As the prime example of a 'living history' group, members of the SCA aim to re-create the past through applying elements of historical knowledge to a practical engagement with Medieval and Early Modern crafts, martial arts, science, metalwork and cooking (for example). The Society was created by graduates of the University of Berkley in California in the 1960s and has since branched out to include 19 kingdoms, with over 30,000 members in locations across the globe.
The Kingdom of Lochac is the regional branch of the Society for Creative Anachronism for individuals living in Australia and New Zealand.
