5,648 residents places Newington squarely in the middle of the New South Wales suburb size distribution (state median 5,325), with market depth comparable to most NSW localities. Median household income of $128,180/year runs 31% above the New South Wales suburb median of $97,552, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Median weekly rent of $560 equates to $2,427/month — about 97% of the median mortgage repayment of $2,500/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. 15 km from Sydney places Newington in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs. Only 37% of dwellings are separate houses (vs 76% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
This suburb suits long-term investors looking for a balance of rental yield and capital growth. Schools and transport underpin family demand. Local rents consume roughly 23% of household income — a useful sanity check on tenant affordability.

That score is driven by a population of 5,648, median household income of $128,180/year and median weekly rent of $560. 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 Newington are proximity to Sydney (15 km), an above-state-median household income of $128,180/year, a dwelling mix that is 37% separate houses, roughly 1 schools and 2 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.
Newington has a usual resident population of approximately 5,648, compared with a New South Wales suburb median of 5,325 — placing it in the upper half of the state's suburbs by size.

Newington sits 15 km straight-line from the Sydney CBD. This is comfortable commuter territory, with reasonable rail and road access to the city.
The most recent census recorded a median weekly rent of $560 in Newington, equating to approximately $29,120/year in gross rental income (state median $430/week).

The median monthly mortgage repayment in Newington is $2,500, or approximately $30,000/year (vs $2,167/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 $560 works out to $2,427/month, covering 97% of the median mortgage repayment of $2,500/month. That leaves a $73/month shortfall (around $876/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 interest-rate sensitivity on the $2,500 median mortgage, a unit-heavy dwelling mix (37% houses) where body-corporate costs and apartment supply affect resale, the broader New South Wales market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
