Many SSIO volunteers participate in Clean-Up Australia Day, a nation-wide annual event organised to clear trash and pollutants on the first Sunday of March.

Young Adults from Victoria, a state devastated by recent wildfires, removed invasive plant species that were infiltrating unburnt sections of parkland. This helped to reduce the work of rangers responsible for the parklands, who were busy dealing with the fire-ravaged areas.

The Australian Capital Territory (ACT) Region adopted a local park. At this park, 30 SSIO volunteers, including SSE students, helped pick up and sort nine large bags of waste.

In New South Wales, more than 120 SSIO volunteers, including SSE children, collected more than 70 bags of litter and recyclable waste, including 10 supermarket trolleys, washing machines, car parts, and other items which were littered along the roads.
