Same security team in Darwin that let through a 6" hunting knife in the bottom of my briefcase; not once but twice. (I'd taken it an earlier camping trip and forgotten it was there. )
In fairness, it got through Sydney security too.
Finally got picked up in Perth, where they allowed me to go back to check-in and put it in the hold. They even gave me a bag to put it in.
