Petermann is a smaller community of 138 — about 5% of the Northern Territory suburb median (3,057) — so investors should factor in the narrower buyer pool and longer average time-on-market. Petermann's median household income of $68,224/year is 40% below the Northern Territory suburb median ($113,308) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Weekly rent of $20 covers just 11% of the median $758/month mortgage repayment, leaving a $671/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. Petermann is 1398 km from Darwin, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 19% of dwellings are separate houses (vs 68% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.

Weak cash flow: $20/week rent covers only 11% of the $758/month median mortgage — a $671/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
Only 19% of dwellings are separate houses (vs 68% NT median) — this is a unit and townhouse market, where cosmetic flips struggle against body-corporate restrictions, thinner after-reno uplift and competing new supply.

Petermann scores 27/100 on our EquitySight investment framework — a weak rating. That score is driven by a population of 138, median household income of $68,224/year and median weekly rent of $20. 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 Petermann are a median household income of $68,224/year, a dwelling mix that is 19% 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.
Petermann has a usual resident population of approximately 138, compared with a Northern Territory suburb median of 3,057 — 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.
Petermann sits 1398 km straight-line from the Darwin CBD. This is a regional market where CBD distance is only indicative — local industry diversity and commute alternatives matter more.
The most recent census recorded a median weekly rent of $20 in Petermann, equating to approximately $1,040/year in gross rental income (state median $360/week).

The median monthly mortgage repayment in Petermann is $758, or approximately $9,096/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 $20 works out to $87/month, covering 11% of the median mortgage repayment of $758/month. That leaves a $671/month shortfall (around $8,052/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 $758 median mortgage, below-median household incomes ($68,224 vs $113,308 state median), a unit-heavy dwelling mix (19% houses) where body-corporate costs and apartment supply affect resale, the broader Northern Territory market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
