Phillip Bay is a smaller community of 721 — about 14% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $114,036/year runs 17% 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. Weekly rent of $313 covers just 48% of the median $2,817/month mortgage repayment, leaving a $1,461/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. 12 km from Sydney places Phillip Bay in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.

Strong buy-and-hold fundamentals: household incomes run 17% above the New South Wales suburb median ($114,036 vs $97,552), and the 12 km CBD distance keeps this suburb in the primary demand zone. In New South Wales, suburbs with this profile have historically clustered in the upper tercile of 10-year capital growth.
Weak cash flow: $313/week rent covers only 48% of the $2,817/month median mortgage — a $1,461/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
With 78% houses in a 721-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 721, median household income of $114,036/year and median weekly rent of $313. 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.

Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Phillip Bay has a usual resident population of approximately 721, compared with a New South Wales suburb median of 5,325 — placing it in the lower half of the state's suburbs by size.

The median monthly mortgage repayment in Phillip Bay is $2,817, or approximately $33,804/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 $313 works out to $1,356/month, covering 48% of the median mortgage repayment of $2,817/month. That leaves a $1,461/month shortfall (around $17,532/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 (721 residents), interest-rate sensitivity on the $2,817 median mortgage, 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.
