Cape Barren Island is a smaller community of 64 — about 2% of the Tasmania suburb median (3,902) — so investors should factor in the narrower buyer pool and longer average time-on-market. Cape Barren Island's median household income of $37,700/year is 49% below the Tasmania suburb median ($73,944) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. The median weekly rent of $85 translates to approximately $4,420/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Cape Barren Island is 284 km from Hobart, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
