NSW 2120 Census 2021 + Live DA Data

Pennant Hills

University qualifications at 60.1% are 30 percentage points above the national average, and every SEIFA index lands at decile 10, the maximum. Yet the $1,801,000 median house price grew only 1.5% in the latest year, near stagnation for a suburb with household incomes in the 91st percentile. The puzzle resolves through the demographic lens: 41.6% born overseas and net overseas migration of +281 per year sustain demand, while net internal outflow of -208 annually drains domestic buyers. Pennant Hills functions as a landing pad for high-income migrants and an exit point for domestic movers seeking cheaper alternatives.

The $1,775,000 to $1,801,000 trajectory (1.5% growth) signals a flattening market after years of premium pricing. Mortgage repayments of $2,700/month produce a 25.6% mortgage-to-income ratio, below stress levels because household incomes ($2,433/week) sit in the 91st percentile. Houses at 73.4% dominate, with 48.3% having 4+ bedrooms. Apartments at 14.9% and semi-detached at 11.5% provide some diversity. Four schools cover primary through secondary: St Agatha's (Catholic, ICSEA 1,147), Mount St Benedict College (Independent, ICSEA 1,147, 1,331 students), Pennant Hills Public (Government, ICSEA 1,143, 490) and Pennant Hills High (Government, ICSEA 1,109, 1,131).

For Investors

Renters at 24.0% provide a moderate tenant pool. Weekly rent of $500 against $1,801,000 gives a gross yield of 1.4%, extremely low even by premium Sydney standards. Vacancy at 6.6% is above average. Development activity at 67 DAs in 12 months is robust, including seniors housing and major renovations. Net overseas migration of +281 per year is the primary demand driver, but net internal outflow of -208 partly offsets this. The 1.5% price growth suggests the premium end of the Hills District is reaching a ceiling. Seniors housing DAs indicate an emerging aged-care niche that may reshape local rental demand.

Outright owners (39.1%) and mortgage holders (36.9%) dominate at 76%, with renters at 24.0%. Houses make up 73.4%, apartments 14.9% and semi-detached 11.5%. The 4+ bedroom segment at 48.3% is the largest, consistent with the family orientation. Prices moved from $1,775,000 to $1,801,000, a 1.5% gain that is essentially flat. Mortgage stress at 25.6% and rent stress at 20.6% are both comfortably below 30%. The 82.4% residential stability rate is high, meaning most families stay long-term. IER decile 10 confirms concentrated economic resources, while the high ownership share explains why capital is locked into property rather than rental markets.

Public transport at 10.1% is well above average for a Hills District suburb, reflecting train access. Car driving at 76.3% is still dominant but lower than comparable areas. Walking/cycling at 6.6% is moderate. Four schools all score above ICSEA 1,100: St Agatha's (1,147, 217 students), Mount St Benedict (1,147, 1,331), Pennant Hills Public (1,143, 490) and Pennant Hills High (1,109, 1,131). This concentration of high-performing schools is a key livability advantage. IRSAD decile 10 confirms top-tier national advantage. The 5.0% need-assistance rate is close to average.

Population Forecast

+0.61%/yr

(+136 people/yr)

Established

Population growth runs at 0.61% per year (136 persons), modest for Sydney standards. The ERP reached 22,248 in 2025, with medium forecasts projecting 23,188 by 2031. Overseas migration at +281/year is the sole growth driver, as internal migration runs at -208/year (net loss). The 10-year population change of 11.9% tracks metro averages. Affordability improved from a mortgage-to-income ratio of 60.2% in 2011 to 50.7% in 2021, driven by income growth outpacing price rises. The young share held stable (+0.2 points) while the senior share grew 2.9 points, indicating gradual aging rather than rapid demographic shift.

What is the median house price in Pennant Hills?

The median is $1,801,000 (2025), up just 1.5% from $1,775,000 in 2024. Monthly mortgage repayments average $2,700 and weekly rent is $500. Gross yield is approximately 1.4%. The mortgage-to-income ratio of 25.6% is manageable because household incomes sit in the 91st percentile nationally.

What schools are in Pennant Hills?

Four schools operate in the suburb: St Agatha's Catholic Primary (ICSEA 1,147, 217 students), Mount St Benedict College (Independent, ICSEA 1,147, 1,331 students), Pennant Hills Public School (Government, ICSEA 1,143, 490 students) and Pennant Hills High School (Government, ICSEA 1,109, 1,131 students). All score well above the national 1,000 benchmark.

Is Pennant Hills safe?

Suburb-specific crime data is not available. However, SEIFA IRSD decile 10 (lowest disadvantage nationally) and the 91st-percentile household incomes are factors strongly correlated with lower crime rates across NSW suburbs. The 82.4% residential stability rate also suggests a settled, low-turnover community.

Is Pennant Hills good for property investment?

Gross yield is very low at 1.4% ($500/week on $1,801,000). Only 24% rent and vacancy is 6.6%. The 1.5% annual price growth is near flat. On the demand side, net overseas migration of +281/year sustains population, and 67 DAs in 12 months show development interest. However, internal outflow of -208/year signals some domestic price resistance.

How is Pennant Hills's population changing?

Growth is 0.61% per year (136 persons), with medium forecasts projecting 23,188 by 2031. Overseas migration (+281/year) drives all net growth, as internal migration runs at -208/year. The overseas-born share at 41.6% is 20 points above national. The senior share grew 2.9 points over the decade while the young share held steady.

What languages are spoken in Pennant Hills?

With 41.6% born overseas, 20 points above the national average, Pennant Hills is linguistically diverse. Mandarin (309 speakers), Cantonese (200), Korean (133), Hindi (69) and Arabic (47) are the top non-English languages, reflecting strong East Asian and South Asian migration into the Hills District.

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.
