1,048 solar installations registered with the Clean Energy Regulator · ranked top 50% in Queensland · data current as at 2026-06-15
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Postcode 4309's 1,048 solar systems typically avoid around 6.49 tonnes of CO₂ every hour during peak generation.

Postcode 4309 ranks 223rd in Queensland for solar installations — in the middle tier of 449 postcodes tracked by the Clean Energy Regulator across the state. 71 new systems were installed in the past 12 months, a 18% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Postcode 4309's solar community avoids an estimated 10,373 tonnes of CO₂ every year — equivalent to taking 4,940 cars off the road or powering around 2,075 average Australian homes with clean electricity. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
