Kumarina is a smaller community of 91 — about 2% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. Household income of $94,224/year is 6% below the Western Australia median of $99,736, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Kumarina is 846 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
