Not really in my experience.
QF goes through periods of enforcement, the last IME was 5 years ago circa 2011. I recollect having a circa 10kg bag gate-checked at SYD even though I was flying J on 767. So it can happen at any time but unlikely these days (except at AKL, as described above; flew BNE-NRT a few months ago and was not checked then at BNE).
