Castle Donnington is a smaller community of 139 — about 2% of the Victoria suburb median (7,416) — so investors should factor in the narrower buyer pool and longer average time-on-market. Household income of $80,132/year is 16% below the Victoria median of $95,160, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Median rent of $250/week (~$1,083/month) covers only 69% of the median mortgage of $1,564/month — the remaining $481/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. Castle Donnington is 293 km from Melbourne, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Limited buy-and-hold upside: a small population of 139 means liquidity is thin and capital growth tends to lag the wider Victoria market over full cycles.
Moderate rental coverage: rent of $250/week covers 69% of a $1,564/month mortgage, leaving a $481/month gap that an investor bridges with equity, depreciation and tax benefits.
With 88% houses in a 139-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

That score is driven by a population of 139, median household income of $80,132/year and median weekly rent of $250.

Castle Donnington has a usual resident population of approximately 139, compared with a Victoria suburb median of 7,416 — placing it in the lower half of the state's suburbs by size.

The most recent census recorded a median weekly rent of $250 in Castle Donnington, equating to approximately $13,000/year in gross rental income (state median $380/week).

The median monthly mortgage repayment in Castle Donnington is $1,564, or approximately $18,768/year (vs $1,950/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 $250 works out to $1,083/month, covering 69% of the median mortgage repayment of $1,564/month. That leaves a $481/month shortfall (around $5,772/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 (139 residents), interest-rate sensitivity on the $1,564 median mortgage, below-median household incomes ($80,132 vs $95,160 state median), the broader Victoria market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
