I had a somewhat related situation with accommodation provided by DJ due to a cancelled flight. My DJ MEL-SYD was cancelled and was the last of the day so they put me up at the Melbourne Airport Hilton and I flew out early the next morning on a DJ flight. I got my points from the actual DJ flight I took, not the original one I was booked on (I suppose because my booking was reissued and then boarding pass printed on the new flight). I enquired later with Hilton if I could claim points for the stay, but they replied that free stays booked by airlines do not qualify for points (fair enough).
In your case, you haven't travelled on your DJ flight so there are no records to record points and you haven't paid for the QF flight so likely no points.
It doesn't seem like a fair situation I know - but if you should get points from anyone it should be DJ and not QF. I would push the matter with DJ.
