Most marine flares have a use-by date of three years and must be replaced before their expiry date.
Because flares contain explosive matter, it's important that you dispose of them safely and legally.
The NSW Government runs a free mobile collection program for expired flares during peak boating season, with temporary collection points set up at boat ramps. Due to COVID-19 restrictions, the next round of collections will take place in January, April and June 2022.
Details of upcoming events are made available on the Transport for NSW website and the NSW Maritime Facebook page.
