Deniliquin
At $345,000 median and a mortgage-to-income ratio of 20.5%, Deniliquin offers some of NSW's most affordable housing, yet the 12.1% vacancy rate and declining population trend (-0.28% per year) reveal why: this is a regional centre losing working-age residents while its senior share grew 5.5 percentage points over the decade. Agriculture (7.9%) remains a significant employer, unusual for this cohort, while healthcare (21.7%) anchors the service economy. The volunteering rate of 21.9%, roughly double the national average, underscores a community with strong social infrastructure compared to metros.

Separate houses account for 89.6% of stock, with 3-bedroom homes at 47.6% and 4-plus bedrooms at 31.6%. The median of $345,000 rose 9.9% year-on-year from $327,500 in 2024 to $360,000 in 2025. Mortgage repayments of $1,083 per month absorb just 20.5% of income, well below stress levels and cheaper than renting in many capital cities. Household income at the 27th percentile ($1,221/week) is low in absolute terms, but the price-to-income ratio is among the best in NSW. Buyers should note the 42.1% outright ownership rate indicates most properties transact between established locals.

For Investors
Renters make up 26.9% of residents, near the national average, but vacancy at 12.1% is among the highest in this cohort, indicating chronic oversupply or seasonal fluctuation. Weekly rent of $230 is extremely low, delivering modest yield against the $345,000 median. Development activity of 97 DAs in 12 months is surprisingly high for a regional town, though most are sheds, demolitions, and agricultural structures rather than residential builds. Balanced migration (33 internal, 21 overseas per year) provides minimal tenant growth.

Prices rose from $327,500 in 2024 to $360,000 in 2025, a 9.9% gain. The 42.1% outright ownership rate reflects an older population that purchased at historically low prices. Mortgage holders at 31% and renters at 26.9% make up the remainder. Rent-to-income at 18.8% and mortgage-to-income at 20.5% are both well below stress levels, confirming Deniliquin as one of NSW's most affordable markets in ratio terms. Semi-detached homes at 9.4% provide limited alternatives. Vacancy at 12.1% is a structural feature of rural markets where housing stock exceeds population demand.

Is Deniliquin safe?
Suburb-level crime data is not available for Deniliquin in the current dataset. The SEIFA IRSAD decile of 2 (bottom 20% nationally) correlates with higher-than-average crime in comparable regional areas. NSW crime data is typically reported at the LGA level.
Is Deniliquin good for property investment?
The $345,000 entry price is low, and 9.9% year-on-year growth is solid. However, 12.1% vacancy and $230 weekly rent produce modest returns. Population is declining at -0.28% per year. The 97 DAs in 12 months are mostly non-residential (sheds, demolitions). Deniliquin suits very long-term holders accepting rural-market liquidity risk.
How is Deniliquin's population changing?
Population is declining at -0.28% per year, losing about 20 people annually. Growth over 10 years was effectively flat at 0.4%. The senior share grew 5.5 percentage points over the decade. Medium projections forecast 6,709 by 2031, down from 7,020 in 2025.
How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
