Cabbage Tree Island is a smaller community of 89 — about 2% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Cabbage Tree Island's median household income of $44,200/year is 55% below the New South Wales suburb median ($97,552) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. The median weekly rent of $210 translates to approximately $10,920/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Cabbage Tree Island is 584 km from Sydney, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Separate houses make up 100% of dwellings — 24 percentage points above the New South Wales median of 76% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.

Limited buy-and-hold upside: a small population of 89 means liquidity is thin and capital growth tends to lag the wider New South Wales market over full cycles.
Gross rent of $210/week (~$10,920/year) sets the yield ceiling. Cross-check against your purchase price to confirm whether this suburb hits the 4–5% gross yield most Australian investors target.
With 100% houses in a 89-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.
