In regards to metadata retention, the shadow Comms Minister at the time outright said Labor had no plans to amend or repeal the legislation if elected.
I don't buy this "they're secretly anti-surveillance!" line. They are complicit.
It's also puzzling how you imply that amending these bills would fix them. As if one more check and balance would make them not a horrific disaster. In fact, Labor's "amendments" to "fix" the AA bill was adding mandatory judge approval for mass surveillance -- sounds fixed to me!
Labor are pro surveillance and have been for a very long time. They have voted for every single surveillance bill. Their MPs ignore feedback about surveillance from constituents.
Implying they should trash fundamental principles by voting for this stuff just to cling to power is pretty weak. They won't change anything, they support it.
The metadata retention bill that Labor vehemently supported has already been viciously abused. Originally touted as being a bill designed to combat terrorism and child abuse, it's now used to investigate things like littering(!!!). Federal police have been caught using it to stalk girlfriends repeatedly. Labor support this.
