the rich suburbs are a nice place to live.
beaches, the river, yacht clubs, 3 bunnings (a guy thing), golf courses, outdoor cinemas (camelot, somerville uwa and moonlight kings park), 15 minutes to freo, 10 minutes to the city, kings park, great restaurants and cafes (high end and university prices), claremont shopping precinct, great markets at UWA and Subiaco, the best schools including quality public schools.
it is a little old school where most shop staff know your name and what you like. I like the fact Tom the greek makes my cakes, Doshi designs my furniture, Tony is my carpenter, Herb is my caterer.......etc etc. You feel like you belong in a place when you know everyone rather than just exist in a place.
The down side is the average age, the ridiculous house prices ($1.5m is probably an entry point and a $3m home will get you something nice, on $3m the stamp duty is another $150k, then another $6k a year land tax plus $4k council rates). The large lawns means water bills of $700 and similar for power. Then add the building maintenance costs of $50k-100k per year.
A place in Shenton Park and parts of Mosman could be a pretty amazing entry point with a much lower price tag but enjoy the same proximity.
