Yep. They can't accommodate such a request on a last minute up-op so you'' be bypassed.

Inspired by this I did a google search. http://www.airlinemeals.net is an amazing resource, though the 2 kosher meals reports on QF which are domestic have one meal which was clearly not kosher (QF forgot to load the Kosher meal) and the second is simply fruit. Hopefully on QF International you receive better service and a better meal.

It would seem that many in the US/EU state that Kosher airline food is of a higher standard.
