Rossmoyne vs Joondalup

Demand 6/10: a prestige, low-turnover riverside suburb (3,638 residents; median age 48; median mortgage $2,741/month) on the Canning River whose defining driver is the Rossmoyne Senior High School catchment — one of WA's elite public-school zones — fuelling very high Chinese-Australian (and growing Indian) family demand and premium prices.

Demand 6/10: major northern hub, but oversaturated with established chains (The Coffee Club, Dome, Gloria Jean's).
