Is it not showing up at all on the QF FF website? If so, then you might phone res and get them to check whether the FF number is in properly. That might be important for seating, if nothing else.

But if you've got a confirmation e-mail that says you've been ticketed, I would have thought that would be good enough. And (unless you're really time critical) you do have the luxury of flying on a route which has, shall we say, a reasonable frequency of service - just in case something has gone wrong and it takes them a little time to sort it out.
