Check out the 2024 annual air quality statement
About
The 2024 annual air quality statement is now available on our website.
The Statement summarises when, where and why pollutant levels exceeded national standards in 2024 by analysing data from 56 of the NSW Government’s compliance air quality monitoring stations across 16 regions.
Despite above average temperatures, higher rainfall totals in 2024 compared to 2023 helped ease drought in New South Wales, leading to better overall air quality with fewer bushfires, dust storms, and hazard reduction burns.
The Lake Macquarie, Central Coast and Southern Tablelands regions never exceeded daily or annual air pollution standards in 2024. All other regions were within national standards at least 97% of the time, except for 2 locations in the Hunter Valley.
Because the Hunter Valley includes several sources of industrial air pollution, the Statement also features a focus study for this part of the state. Compared to 2023, the air quality monitoring stations at Stockton, located near the coast and subject to high levels of sea salt spray, and Warkworth, located near mining operations, had fewer particle exceedance days.
