Multiple outlets report that Perth’s most expensive streets are concentrated in the inner suburbs of Dalkeith and Cottesloe, with the highest-valued location appearing in Peppermint Grove. The coverage identifies Peppermint Grove as home to the top entry on the list, where homes are reported to be nearly $10 million. The articles note that Dalkeith and Cottesloe contain most of the streets ranked among Perth’s most expensive, indicating a clustering of higher property values in those areas. While the reports focus on street-level pricing, they present a consistent overall pattern: the upper end of the market is dominated by these coastal and nearby suburbs, rather than being spread evenly across the city. Across all sources, the main shared details are the ranking emphasis on Dalkeith and Cottesloe, and the placement of Peppermint Grove at the top, with a headline figure just under $10 million for homes on the most expensive street.
