All countries have positives and negatives, good things and bad.I don't know anything about Australia but you sound fortunate. (Exhaustive example: I have a cousin by marriage who moved there from the States for the schools and he is very happy. His son has flourished in cricket!) But our cities are becoming very unsafe for failure to enforce laws combined with domestic and illegally imported criminals. Security, from crime and foreign militaries, are the core responsibilities of our governments. They aren't doing the former very well. Plus there have been assassinations and their attempts. I hope for a change since the liberal tradition is too valuable to squander.
We are lucky that we are a remote island, but mostly that we tend to have a good sense of humour and don't take things, or ourselves, too seriously.
Houses are very expensive but wages are good and so is work life balance in general.
we work to live and not live to work.
We are also a lot more accepting of other people's cultures and backgrounds in general.
Thankfully religion is going away as it is the No1 cause of conflict in the world.
Although we tend to respect people have the right to practice whatever religion they want, just keep it to yourself.
The number of Australians who identified as having no religion increased again this census (38.9%), rocketing up from 30.1% in 2016.
Crime is relatively low by world standards, however domestic violence is an issue.
Knowing that it is highly unlikely that someone will be armed with a gun certainly makes everyone more relaxed and has a huge impact on police attitude as well.
Recent death of 2 police officers is seen as a real tragedy and unacceptable.
