Mambourin is a smaller community of 315 — about 4% of the Victoria suburb median (7,416) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $122,668/year runs 29% above the Victoria suburb median of $95,160, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Rent of $363/week (79% coverage of the $2,000/month median mortgage) leaves a gap of roughly $427/month that a typical investor bridges with negative gearing, depreciation and capital growth. At 37 km from Melbourne, Mambourin is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.

That score is driven by a population of 315, median household income of $122,668/year and median weekly rent of $363.

Mambourin has a usual resident population of approximately 315, compared with a Victoria suburb median of 7,416 — 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.
Mambourin 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.
The most recent census recorded a median weekly rent of $363 in Mambourin, equating to approximately $18,876/year in gross rental income (state median $380/week).

The median monthly mortgage repayment in Mambourin is $2,000, or approximately $24,000/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 $363 works out to $1,573/month, covering 79% of the median mortgage repayment of $2,000/month. That leaves a $427/month shortfall (around $5,124/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 (315 residents), interest-rate sensitivity on the $2,000 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.
