Perhaps a non-Qantas/other Australian airline crewmember could advise which alternate would have been carried for Sydney given the forecast used by the QF108 on the 12th - before any mention of fog.
In particular it would be interesting to know if other A380 operators carry something other than Melbourne or Brisbane when Sydney is the destination.
A conversation some years ago with a friend at another major (Asian) airline suggested to me that they carry Williamtown or Richmond for Sydney and Avalon for Melbourne.
Personally I've never found the Qantas fuel policy has been deficient primarily because any discretionary fuel that I choose to add is rarely, if ever, questioned; something that was not the case for my friend mentioned above.
