Again, be realistic, and account for the context of the situation. The LNP, in cahoots with our corrupt media made this a "keep Aussies safe over Christmas" issue.
No one in Australia is strong enough to take on the Murdoch media cabal. If Labor opposed, and even a minor incident occurred over Christmas they would have jeopardized their chances of election. For what? An issue that the vast majority of Australians don't care about? Idiocy.
I'm as disappointed as any other punter, but I've been unable to convince any of the tech-illiterate in my social circle that it matters.
Which is even more disingenuous when you consider that the bill won't even take effect until March, and probably won't lead to any backdoors until significant time after that.

How do you win in this scenario?
Honestly, I don't know how we could possibly win in this scenario. A corrupt media stoking unfounded fears in an ignorant public is a very powerful thing.
It depends how you present things, get some press release that say: "The Australian government knows all about your visits to Youporn" would talk to people way more than "Australia new encryption law". About that, see the episode about government surveillance on last week tonight that tries to explain all the NSA programs when it comes to dick picks: https://www.youtube.com/watch?v=XEVlyP4_11M
Saying they would "die on their sword" is wrong. Nobody would care if they said "we're waiting 6 months because we want time to debate". They do that sort of thing all the time, doesn't raise a blip. This is a fringe issue! Nobody understands or cares about cybersecurity, that is the only reason that they can get something like this passed.
To claim the Liberals would run a scare campaign is one of the most baldfaced lies since "I thank the honorable [opposition] member for their question" in parliamentary Question Time. Scare campaigns don't need to be run based on facts, politics has moved beyond that. If a scare campaign is in the works it will go ahead regardless. Labour are still going to get called soft on crime if the Liberals think it will win them votes.
