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.
