The US government and their agenda to spread similar laws in their country and across the world.
Labor was always on board with the core of the legislation; likely as they were aware of some unreported Five Eye's agreement that Australia will be the 'thin edge of the wedge' to introduce such laws worldwide.
Any amendments proposed wouldn't have changed the goal and was simply the basis for some political theatre to look like such a law has been considered and debated by the politicians. The outcome had already been decided a lot earlier than that point.
Voters? I don’t mean to be snarky, but while Tweets, submissions and letters may inform the content of bills in democracies, but the counts of these are not numerically representative of much, apart from the feelings of people who feel strongly about an issue.
That said, these laws sound exceedingly stupid.
For me, this was the 50tone block of concrete on the lead coffin on the rotting cadaver of a political system that serves humanity in a balanced manner.
The same interests they are always representing. Themselves. The organisations and lobbyists that got them voted in. The organisations they're looking forward to offers of high-priced consultancies and directorships after the next election.
Did you expect anything else?
Today I watched my country's democracy die via livestream, with the words "Labor withdraws all amendments".
