The government has effectively made it possible that anyone and everyone who develops software or hardware used by anyone in the country, or where they feel national security comes into play, must compromise their software, and tell no one.
They can ask any intern to break the software, and not tell their employer.
It's bad enough to have a gaping hole in your security, but now they can ask people who have no idea what they're doing to create a backdoor.
All Australian software has now been rendered completely untrustworthy, and when those compromises in security are found, by the nation states who now know that Australian software will have holes in it, it will result in the very thing that this bill claims to prevent.
Our infrastructure has been opened up for attack, by any of our neighbours who have a reason to do so, whilst simultaneously gutting the economy of IT in Australia. Who wants to buy shitty backdoored Chinese software? It's the same now for Australia.
Australia's government has now opened the door for widescale cyberterrorism to have a chance at wreaking destruction.
