Undoolya is a smaller community of 11 — about 0% of the Northern Territory suburb median (3,057) — so investors should factor in the narrower buyer pool and longer average time-on-market. Undoolya's median household income of $23,400/year is 79% below the Northern Territory suburb median ($113,308) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. The median weekly rent of $20 translates to approximately $1,040/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Undoolya is 1289 km from Darwin, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
