Thank you everyone for all the comments here! I don't even know the existence of Perth until I watched this video!! (Yes, I am an American....) Very interesting on how people want to move there. It is similar to people moving from places like New York City or Los Angeles to midwest cities.
I lived in Australia (Sydney) for 2 years (to gain the Passport) in early 90's. I have never visited Perth. I have visited Alice Spring, Melbourne, Great Barrier reef, Gold Coast etc. Thank you for sharing this information.
