Sydney was the best city on the planet but it's changed.
I saw many changes, lots of barbaric people arrived in Australia illegally.
In the 90's, I worked for projects team, an engineer involved with the City Rail CCTV installion, I was 24hr on call for the police, if there was an incident I would be called out to different locations to download video footage before network was operational.
The Skaf brothers (google has a few videos) and their middle eastern friends, raping those school girls at the train stations and elsewhere, horrendous.
I decided to get out of Sydney and work offshore, living in Thailand since.
All my friends and family moved to QLD.
