At each such conference, Masonic research papers are presented. The Affiliate Research Lodges of each Jurisdiction are enabled to put forward the name of one distinguished Masonic researcher every two years (in 2006 this was extended to two from New Zealand) who delivers his lecture during a 90-minute period at the Conference. He is then designated as a Kellerman Lecturer (KL). In an Australasian sense, Kellerman Lectures are analogous to the prestigious Prestonian Lectures in England, except that the former are awarded only every two years.
