Yeah, well……we kinda did really.
Don’t get me wrong, I think something needs to be done to provide a balance for genuine law enforcement requirements, but as we have seen with technology related legislation of the last few years, it is generally not very good and not really what was sold to the Australian public (looking at you metadata retention legislation!). If a bad actor truly wants to avoid the impact of this legislation they just use a third party encryption product readily available in their multitudes via Google.
Technology related legislation is necessary but it takes time and it also takes consideration of what type of society we want to create for ourselves. Both of which have yet to surface so far.
