Good question posed here which will have long term implications for Perth as Chinese will gradually make up an increasing percentage of new buyers. I think Chinese in general will be attracted to three things - money; food and education.
The classic money suburbs for rich Chinese will be Dalkeith, Nedlands, peppermint grove etc. The best Chinese restaurants in Perth are by and large South of the River, so think willeton to Melville. The best private schools are from Claremont to Mosman Pk to City beach. The best public schools are Rossmoyne, Willeton, churchlands.
Another way of looking at it is where are the Chinese less likely to buy? Well, generally again, they're not hugely into water sports and outdoors activities. So Northern western suburbs are less of an attraction, which is a pity as this is where I'm invested!
