Sinagra

Demographics

The median age of 31 is 9 years below the national figure, one of the most pronounced youth skews in the Perth northern corridor. Overseas-born residents reach 38.4%, which is 16.8 percentage points above the national average, with English ancestry leading at 1,253 residents, followed by Irish (299), Scottish (267) and Italian (203). Non-English languages spoken include Afrikaans (31), Gujarati (20), Punjabi (16) and Mandarin (15), reflecting the suburb's multicultural inflow. Average household size of 2.9 is 0.4 above national, consistent with the dominance of couples with children, who make up 1,475 of 2,705 total families recorded. University qualifications at 25.6% sit 4.5 points below the national figure.

Almost every dwelling in Sinagra is a separate house: 97.3% compared to far lower shares in most metropolitan suburbs, which means detached housing supply and demand are tightly linked here. The tenure split is 65.4% mortgaged, 21.7% renting and 12.9% owned outright, a profile consistent with young families taking on long-term loans rather than downsizers or investors holding free-and-clear assets. Large homes dominate: 68% have 4 or more bedrooms and 30.8% have 3 bedrooms, with only 1.1% at 2 bedrooms. Weekly rent of $400 and monthly mortgage repayments of $1,999 both remain below the stress thresholds on income ratios of 18.5% and 21.4% respectively, meaning housing costs are manageable relative to local incomes.

Community Profile

Economy & Employment

Healthcare is the dominant employer at 19.3% of the resident workforce (212 workers), followed by Construction at 12.5% (138) and Education at 9.5% (104), with Public Administration at 8.5% and Retail at 7.7%. By occupation, Professionals lead at 281, followed by Clerical and Administrative at 225, Community and Personal Services at 215, Labourers at 163 and Managers at 160. The employment base suggests residents largely commute to jobs in the broader northern suburbs rather than working locally. Full-time employment runs at 68.7% of employed residents, and the unemployment rate of 4.4% is modest. IRSD sits at decile 6 and IRSAD at decile 6, both near the national midpoint, while IER reaches decile 8, reflecting relatively strong economic resources despite the mid-range disadvantage ranking.

Transport to Work

Transport use is almost entirely car-dependent: 91.7% of residents drive to work, and only 2.9% use public transport, below the national average for metropolitan suburbs. This reflects Sinagra's location in the northern Perth corridor where rail and bus coverage is thinner than closer suburbs. No schools are recorded within the suburb boundary, so families rely on nearby institutions in Wanneroo, Banksia Grove and Joondalup. Housing stress is low, with rent-to-income at 18.5% and mortgage-to-income at 21.4%, both below the 30% stress marker. IRSAD sits at decile 6, roughly mid-range nationally, and only 3.1% of residents (93 people) need daily assistance. Volunteering runs at 11.4%, indicating moderate community engagement compared to higher-decile suburbs.

Population Forecast

Sinagra's population expanded 8.2% over the past decade, above many comparable Perth northern corridor suburbs, driven by overseas migration averaging 224 net arrivals per year while internal migration runs at minus 46 annually. Annual growth of 2.16% adds roughly 327 people per year. Medium forecasts project the broader area rising from 15,154 in 2025 to approximately 17,560 by 2031. Affordability improved from 55.8% in 2011 to 46.6% in 2021, and the gentrification score sits at early signs stage. Real incomes declined 5.0% over the decade, a counter-signal worth monitoring as mortgage serviceability depends on sustained income growth.
