The situation in Australia is that everyone who officiates at a motorcycle meeting of any code, must be licenced (no cost). Risk management is number one priority. There are four levels of accrediation, the lowest level zero where an official works under supervision, level 1, club meeting,etc, level 4 for international meetings, this accrediation covers everyone from marshals to Clerk of Course. We cannot go up a level until we have officiated at meetings and attended compulsory seminars and completed assesments. The cost of these seminars are met by each state's governing bodies (i.e. the equivalent to your ACU). We get no monitary rewards, just do it for the love of the sport, but fully understand the responsibities involved.
