A large Asian carrier was fond of adding additional checklist items each time they had an incident, or learned of an incident at another carrier. The result was that their checklists were about 4 times longer than the manufacturers
Unfortunately the RAAF has the same philosophy when it comes to check lists.
The important thing to understand is that a checklist is not a "do list"; actions should be accomplished from a flow pattern, with the checklist as a final filter for the "gotcha" items.
Again, another point that the RAAF doesn't get.
