Got picked up by security X-ray at Perth yesterday, trying to inadvertently carry a 7" knife through the checkpoint in a computer bag. (My fault, I'd forgotten it was in there.)
Rather than having it immediately confiscated, I was simply advised to check it in as baggage.
I was treated very politely, to the extent that the security officer concerned suggested I use a 'free pack' rather than the computer bag to check the knife in.
Of more concern was that I'd unwittingly carried the bag, with knife, through Darwin security a week before but was only pulled up for having metal plates in my shoes.
