My understanding, for Qld at least, is that security or screen doors installed when the legislation regarding this didn’t exist, or allowed them at the time, and they are okay to keep. Our annual checks only look at the door proper (including closure integrity, locks, and peep holes and other things they won’t pass). Old screens are not considered and though dangerous for the reasons stated above, can be easily busted or sawn through by the Firies so they let the older one be. That suits me as with all the recent break-ins I’m happy for another layer to be between me and them.
