NSW 2280 Census 2021 + Live DA Data

Belmont South

Sitting at the 27.4th income percentile nationally while carrying a $905,000 median house price, Belmont South faces a notable affordability tension. The suburb's median age of 48 is 8.0 years above the national figure, making it one of the more senior-skewed coastal communities in the Lake Macquarie area. With 80.5% separate houses and a 38.4% renter share, the housing stock is predominantly detached and increasingly tenanted. SEIFA scores place the suburb in decile 2 for IRSAD and IEO, below 80% of Australian suburbs on advantage measures, which shapes the local economy and the profile of residents who stay: 78.3% did not move in the five years to the last census.

The median house price of $905,000 sits well above the income base, with household income in the 27.4th percentile nationally. Mortgage repayments average $1,835 per month, producing a mortgage-to-income ratio of 34.2%, above the 30% stress threshold. Prices eased 1.6% from $915,000 in 2024 to $900,000 in 2025, so buyers face a modest softening market rather than a rising one. The stock is 80.5% separate houses, with semi-detached at 13.0% and apartments at just 3.7%, meaning most buyers are targeting standalone homes. Three-bedroom dwellings dominate at 52.5%, followed by 4-plus bedroom at 18.2%, so the typical purchase is a mid-size family home. Outright owners at 32.9% outnumber mortgage holders at 28.7%, suggesting a stable incumbent base with limited distressed selling.

For Buyers

Outright owners at 32.9% outnumber mortgage holders at 28.7%, suggesting a stable incumbent base with limited distressed selling.

For Investors

A 38.4% renter share gives landlords a broad tenant pool, but the $273 weekly rent is low relative to the $905,000 median, implying a gross yield under 1.6%, below most regional NSW benchmarks. The 6.7% vacancy rate is elevated compared to a healthy 2-3% range, signalling some softness in tenant demand. Development activity is modest with 13 applications in the past 12 months. Migration dynamics are balanced: overseas arrivals add 146 residents per year and internal outflows remove 146, leaving net nil migration. Population grew 10.2% over the decade at a slow 0.5% annual rate. The gentrification score of 50 indicates active upward pressure, while real income growth of 23.0% and improving affordability from 45.8% in 2011 to 43.8% in 2021 suggest gradual structural improvement, though investment returns remain yield-constrained.

Demographics

The median age of 48 is 8.0 years above national, and the suburb's identity signals lean toward an aging, Anglo-dominant, slowly growing community. English ancestry leads at 448 residents, followed by Scottish (135) and Irish (110), with overseas-born at just 8.3%, which is 13.3 percentage points below the national figure. University qualifications reach 19.9% of residents, some 10.2 points below national, reflecting a trade and services workforce rather than a knowledge-economy one. Average household size of 2.3 is marginally below national by 0.2. Couples without children make up 31.6% of families, consistent with the older age profile. The volunteering rate of 9.1% and need-assistance rate of 7.6% (77 residents) align with a settled, moderately aged community.

Tenure is spread across outright owners (32.9%), mortgage holders (28.7%) and renters (38.4%), with renters slightly elevated compared to many established coastal suburbs. The stock is firmly detached-house dominated at 80.5%, with only 3.7% apartments, meaning price movements here track detached house demand closely. Three-bedroom homes account for 52.5% of dwellings and 4-plus bedrooms 18.2%, with 2-bedroom homes at 21.7%. The median house price slipped 1.6% from $915,000 in 2024 to $900,000 in 2025. Mortgage repayments at $1,835 per month and a mortgage-to-income ratio of 34.2% exceed the stress threshold despite household incomes sitting at the 27.4th percentile nationally, creating real affordability pressure for recent buyers. Rent-to-income at 22.0% remains below the 30% stress line for tenants.

Economy & Employment

Healthcare dominates local employment at 24.6% (69 workers), followed by Construction at 14.6% (41) and Education at 11.0% (31), with Public Admin and Other Services each at 6.0%. By occupation, Community and Personal workers lead (81), ahead of Labourers (62), Clerical/Admin (57) and Professionals (56). The unemployment rate of 9.1% is above typical suburban benchmarks, and the participation rate of 51.3% is low, with 382 residents not in the labour force, a pattern consistent with an aging population where retirement reduces active workforce participation. Household incomes sit at the 27.4th percentile nationally. SEIFA decile 2 on both IRSAD and IEO confirms structural disadvantage relative to most Australian suburbs, though real income growth of 23.0% over the decade shows the base is rising.

Transport to Work

Car dependency is extreme at 92.4% of residents commuting by car, and walking or cycling accounts for just 1.0%, well below national averages. No schools are recorded within the suburb boundary, so families depend on institutions in surrounding Lake Macquarie suburbs. Crime data is not available in the current dataset for Belmont South. The IRSAD decile 2 score places the suburb below 80% of Australian communities on a combined index of advantage and disadvantage, indicating meaningful socioeconomic constraints on local services and amenity. Rent-to-income at 22.0% keeps housing costs manageable for the 38.4% of residents who rent, and the residential turnover rate of 21.7% over five years suggests a moderately stable community where most people choose to stay.

Established

Belmont South's population sits within the broader Lake Macquarie SA2, which tracked 14,962 in 2023 rising to 15,227 in 2025, a 10.2% gain over the decade at roughly 0.5% per year. The medium forecast projects the SA2 reaching approximately 15,645 by 2031. Overseas migration contributes 146 arrivals annually, exactly offsetting the internal outflow of 146, so growth depends entirely on natural increase. The shift trajectory is classified as Stable, with a working-age share that grew 0.9 points and a senior share that fell 0.8 points over the decade, a mild demographic improvement. The gentrification score of 50 with an Active stage signals that affordability and income improvements are occurring, even if the suburb has not yet crossed into a higher advantage tier. Affordability improved from 45.8% in 2011 to 43.8% in 2021.

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.
