Also look at route structure. Of all the majors, QF (apparently) have the fewest global destinations on their network - you could therefore argue that their threat exposure is significantly lower than other airlines flying all around Asia/Africa/S.America etc and this would certainly keep them up at the top. Maintenance standards are obviously high though and they identified very early on during QA assessments that the threat from fake parts coming from a few dubious countries warranted a major shift in focus and I believe it was they who set the standard for tracking non-OEM parts.
As has been alluded to, accident reports are not the true indicator of safety. Not 1 airline publishes any information on "almost" events that were saved by crew actions!
