Not sure if the AOC you found on the CASA website is the same as the one I found by searching under 'operators', but it seems to be dated 16 September 2009 and at least 5 of the current fleet (VUR,VUS,VUT,ZPN,ZPO) are also missing from the list.
bagchucka's rumour suggested the type additions occured 'last week' (as at the 14 January 2010), so I would assume an updated AOC would be necessary for the mythbusters to claim 'BUSTED'
