As a new resident to Peppermint Grove I can say that if you aren't from the area you can really be ostracised. I recently moved to Perth from the UK and I set up house on Keane Street.
The houses are big, the streets are clean and the people are as artificial as their front lawns.
I remember the first night I moved in I decided to take a walk down to the Esplanade and cut via View Street. As I was walking along the path I noticed two typical "Western burbs housewives" they very blatantly stopped talking as I approached and turned their heads as I walked past towards my direction.
They may not be used to seeing people of certain colour walking through their beloved neighbourhood but it is downright ignorant of them. It's very clear that they live in their own little self-absorbed warped world of self-importance. The men in the neighbourhood are all very polite when greeting whilst passing in the street. Maybe the "housewives" have a bee in their bonnet because they had to do undesirable things to secure a rich husband. Like all properly exclusive suburbs. The man makes the cash so the wife can flaunt her pretentions.
The only main trait is that they're all very wealthy! I attended Cottesloe Primary School and each family was different. You do get a lot of stuck-up parents, but then you also get a lot of hands on mothers who just want to be involved in their child's life.
