Investment Insight
With 38,851 residents, Sunbury is one of Victoria's more populous suburbs — roughly 5.2× the state median of 7,416 — giving it a deep buyer and tenant pool that typically supports higher transaction volumes and shorter average days on market. Households here earn $100,100/year on average — 5% above the VIC suburb median of $95,160 — a modest premium that supports resilient owner-occupier demand. At the 2021 Census, median weekly rent of $361 equated to $1,564/month — about 90% of the then-median mortgage repayment of $1,733/month. Both figures have moved substantially since 2021, so treat the ratio as a historical signal that this suburb leaned cash-flow-friendly, and verify against current listings and rates. At 37 km from Melbourne, Sunbury is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.
Investment Tip
Regional property can deliver strong cash-flow yields but liquidity is tighter — plan for longer hold periods and verify local employment stability. At the 2021 Census, local rents consumed roughly 19% of household income — a dated but useful sanity check on tenant affordability.

Investment Strategy
Solid buy-and-hold profile: a population of 38,851 and household income close to the VIC median ($100,100 vs $95,160) give the market enough depth for patient capital growth without the premium entry price of inner suburbs.
Strong rental coverage at the 2021 Census: $361/week (~$1,564/month) covered 90% of the $1,733/month median mortgage, a shortfall of just $169/month. Both rents and repayments have moved since 2021 — verify current figures, though this suburb has historically leaned cash-flow-friendly.
With 84% houses in a 38,851-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.
Risk Factors
- Interest-rate sensitivity: the $1,733/month median mortgage in Sunbury means a 1-percentage-point RBA rate rise could add roughly $173/month to repayments, reducing buyer borrowing capacity and cooling prices.
- Sunbury is 37 km from the CBD — not close enough to benefit from the inner-ring pricing halo, so growth depends more heavily on local infrastructure decisions and the wider Victoria market cycle.
- Regulatory risk: changes to Australian tax settings (negative gearing, CGT discount, foreign-buyer surcharges, land-tax thresholds) could reshape after-tax returns in Sunbury regardless of local market conditions.
- Market cycle risk: property markets are cyclical, so stress-test your projections in Sunbury with a 10–15% price pullback scenario before committing capital — returns to date are not a guarantee of future performance.

Whether Sunbury suits you depends on your strategy, but the fundamentals are concrete: a population of 38,851, a median household income of $100,100/year and median weekly rent of $361. Weigh those against your goal — cash flow, capital growth, or a value-add renovation — each of which we break down with suburb-specific ABS numbers elsewhere on this page.
What drives property demand in Sunbury?
The main demand drivers in Sunbury are an above-state-median household income of $100,100/year, a dwelling mix that is 84% separate houses. Together these shape both owner-occupier and tenant demand.
What is the population of Sunbury?
Sunbury has a usual resident population of approximately 38,851, compared with a Victoria suburb median of 7,416 — placing it in the upper 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.
How far is Sunbury from the Melbourne CBD?
Sunbury sits 37 km straight-line from the Melbourne CBD. This is an outer-metro location; local employment and infrastructure announcements tend to move prices more than CBD connectivity alone.
What is the median rent in Sunbury?
The most recent census recorded a median weekly rent of $361 in Sunbury, equating to approximately $18,772/year in gross rental income (state median $380/week). Market rents have typically drifted above the recorded figure — verify against current listings on realestate.com.au and Domain before making an offer.
What is the typical mortgage repayment in Sunbury?
The median monthly mortgage repayment in Sunbury is $1,733, or approximately $20,796/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.
Is Sunbury cash-flow positive for investors?
A median weekly rent of $361 works out to $1,564/month, covering 90% of the median mortgage repayment of $1,733/month. That leaves a $169/month shortfall (around $2,028/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.
What are the main risks of investing in Sunbury?
The main risks are interest-rate sensitivity on the $1,733 median mortgage, the broader Victoria market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
