There are many other professional associations world-wide set up either exclusively for Reiki practitioners or which include Reiki practitioners among their members. Here are those with whom the UK Reiki Federation currently has a link:
Australian Reiki Connection Inc
A nationally incorporated not for profit Reiki association, run by members for members, since 1997. ARC is an association of people who are dedicated to working with and promoting the 'Spirit of Reiki', through teaching, healing, fellowship and research, both within the Reiki Community and the Wider Community.
