Above average rainfall in Australia has led to a higher risk of bushfires, prompting health organisations and fire services to issue warnings about air pollution. Hazard-reduction burns, conducted to reduce the risk of fires, release fine particles and toxic gases into the air which can have significant health impacts, particularly for those with lung conditions. Exposure to smoke can exacerbate existing health issues, impair lung function, and increase hospitalisation and death rates. There is no safe level of air pollution. It can also lead to conditions such as lung cancer, pneumonia, heart disease, stroke, worsened asthma, and respiratory conditions, as well as being linked to other diseases. It can also affect people with heart disease or who have previously had a stroke. It is crucial for individuals with lung health issues to have a plan in place with their doctors to respond to any deterioration in symptoms. This may involve identifying cleaner air spaces, closing doors and windows, or using air purifiers.
For those in areas impacted by controlled burns, the Lung Foundation Australia recommends checking real-time air quality, paying attention to air pollution alerts, reducing physical activity outdoors, wearing face masks, resting more often, attending regular health check-ups, exercising regularly, switching the air conditioner to recirculate mode, ensuring medications are topped up and in date, and having an emergency plan ready in case of evacuation or the loss of essential services.
Due to increased fuel growth caused by above-average rainfall in recent La Niña years, many Australian regions are facing an increased risk of bushfires. Large areas of central and northern New South Wales, in particular, are expected to have a heightened fire risk in the upcoming season. In preparation, hazard reduction burns have been undertaken where permitted. The Rural Fire Service advises homeowners to trim overhanging trees and shrubs, clear material that can burn around the home, remove debris and leaves from gutters, and ensure they have a working hose or hoses that can reach all areas of the property. State Emergency Services Minister Jihad Dib emphasizes the importance of taking simple steps to prepare for the season, including reducing vegetation around properties, cleaning gutters, and having a plan in place for evacuation.
