Diamond Tree is a smaller community of 28 — about 0% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $123,448/year runs 24% above the Western Australia suburb median of $99,736, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Diamond Tree is 268 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
