Abernethy is a smaller community of 317 — about 6% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $107,588/year on average — 10% above the NSW suburb median of $97,552 — a modest premium that supports resilient owner-occupier demand. Median weekly rent of $360 equates to $1,560/month — about 100% of the median mortgage repayment of $1,560/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. Abernethy is 111 km from Sydney, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Separate houses make up 99% of dwellings — 23 percentage points above the New South Wales median of 76% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.

With 99% houses in a 317-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

A median weekly rent of $360 works out to $1,560/month, covering 100% of the median mortgage repayment of $1,560/month.
