In what class? There are 3 rather different menus on any one flight. QF does serve a full meal on these late night departures. The menus vary seasonally but are similar to past menus posted on FT, for example http://www.flyertalk.com/forum/showthread.php?t=81105
or you can search for others if that doesn't suit you. If your flight is after June 1 these are as likely to be accurate as any "recent reports" from the specific flight numbers.
