Recent (2018) Australian data encryption laws are insane and archaic. It allows law enforcement to force individuals (including but not limited to developers) or companies to build a back door and requires them not to tell any one, including their employers. I'm not saying the US is better or worse, or that the UK (where I live) is better or worse. I'm raising awareness as not a lot of people know about their data encryption laws.
Personally I'd wanted to move to Australia but stopped chasing that due to their data encryption laws.
And what can the Australian government do that the US government can't these days?
