Koonya is a smaller community of 138 — about 4% of the Tasmania suburb median (3,902) — so investors should factor in the narrower buyer pool and longer average time-on-market. Koonya's median household income of $52,520/year is 29% 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. Weekly rent of $115 covers just 42% of the median $1,183/month mortgage repayment, leaving a $685/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. At 46 km from Hobart, Koonya is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price. Only 65% of dwellings are separate houses (vs 80% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.

Whether it fits your portfolio depends on whether you are targeting cash flow, capital growth, or a value-add renovation — all three are scored with suburb-specific numbers elsewhere on this page.
The main demand drivers in Koonya are a median household income of $52,520/year, a dwelling mix that is 65% separate houses, roughly 1 schools and 1 parks within the catchment. Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Koonya has a usual resident population of approximately 138, compared with a Tasmania suburb median of 3,902 — placing it in the lower half of the state's suburbs by size. Population is the clearest proxy for market depth: more residents mean more transactions and typically a shorter average days-on-market on resale.
Koonya sits 46 km straight-line from the Hobart CBD. This is an outer-metro location; local employment and infrastructure announcements tend to move prices more than CBD connectivity alone.
The most recent census recorded a median weekly rent of $115 in Koonya, equating to approximately $5,980/year in gross rental income (state median $320/week).

The median monthly mortgage repayment in Koonya is $1,183, or approximately $14,196/year (vs $1,378/month state median). Stress-test your own borrowing at rates 1–2 percentage points above today's to make sure you can still service the loan through an RBA tightening cycle.
A median weekly rent of $115 works out to $498/month, covering 42% of the median mortgage repayment of $1,183/month. That leaves a $685/month shortfall (around $8,220/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared. Actual cash flow depends on your deposit, loan terms, ownership costs and marginal tax rate — run the full numbers in our rental yield calculator.
The main risks are a thin buyer pool (138 residents), interest-rate sensitivity on the $1,183 median mortgage, below-median household incomes ($52,520 vs $73,944 state median), the broader Tasmania market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
