Economy & Employment

Construction leads the local employment mix at 20.5% of workers (81 people), reflecting both the suburb's semi-rural setting and its proximity to growth corridors in the northwest of Sydney. Education follows at 17.2% (68 workers) and Healthcare at 10.9% (43 workers), together giving the local economy a service-sector character.

Full-time employment runs at 64% of employed residents and the unemployment rate is 3.3%, below the national average. Real incomes grew 14.8% over the decade. The suburb's SEIFA IRSAD decile of 9 places it in the top tenth nationally for combined advantage.

Transport to Work

Car dependence in Windsor Downs is near-total: 93.2% of residents drive to work, above the national figure, because public transport options are limited across the 7.58 km2 low-density footprint. Only 1.5% walk or cycle. The suburb scores decile 9 on IRSAD nationally, placing it in the top tier for advantage and consistent with low disadvantage. Housing stress is absent: rent-to-income sits at 16% and mortgage-to-income at 22%, both comfortably below standard stress thresholds. The volunteering rate of 14.5% suggests a moderately engaged community. No schools are recorded within the suburb boundary in this dataset, so families depend on nearby services in the broader Windsor area. Only 4.4% of residents (50 people) need daily assistance.
