The Kingdom of Lochac comprises all SCA groups in Australia and New Zealand (as of Lochac May Crown, 2003).
The Australian groups were previously the Principality of Lochac, part of the Kingdom of the West. The New Zealand groups were formerly part of the Kingdom of Caid.
When SCA groups in a region fulfil certain criteria (as enumerated in Corpora), they can become a kingdom, provided sufficient members wish to do so. This occurred in Australia in July 2002.
Lochac's Crown tournaments occur during May and November.
