Ozgrade, it all comes down to the FOI who decides what the checklist will be, and how it will work. Most FOI's prefer read and do as that is the only experience they have to draw on from their local aero club. There is no way anyone can get a proffessional scan flow do then read checklist approved in Australia, unless its supplied by the manufacturer and then there's no guarantee the FOI of the day wont require you to muck about with it.
I've seen before start checklists that take twenty minutes to complete for a simple light jet, and before landing checklists that can take the entire ILS from locator to minima to complete. If the before landing checklist for an airbus contains two items, for a citation the FOI will require forty. Its unproffessional, distracting and dangerous, but thats CAsA for you, they really should take that "s" out of their name.
