The BMAA used to produce an accident/incident report in a booklet with their magazine. Nowadays it is produced on-line. However it still keeps you current with letting you know what other pilots had 'forgotton' on their check-lists etc. close calls and other relevent information. It doesn't have to be an accident to learn from the information.
RAA have their own Accident Investigators (the last course I believe, was held in 2009). They are all equipped (or share within a group) with investigation kits that they take with them. They are there to assist the police, gather the information and report back to the RAA office.
Maybe they need to conduct some more courses at Canberra?
