Arnold is a smaller community of 75 — about 2% of the Northern Territory suburb median (3,057) — so investors should factor in the narrower buyer pool and longer average time-on-market. At $107,848/year, household income in Arnold is within 5% of the Northern Territory median ($113,308), placing the suburb firmly in the state's mainstream demographic band. Arnold is 553 km from Darwin, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
