MCCG operates with around 50 management volunteers, over 100 regular volunteers, and more than 400 annual members. The group works with Brisbane City Council, landholders, and neighbouring catchments to restore bushland, which forms the southern foothills of D'Aguilar National Park. Positioned between Brisbane and one of Queensland’s busiest national parks, MCCG plays a key role in wildlife surveys, waterway monitoring, and creating habitat corridors for fauna to safely move through the catchment into the park.
MCCG’s nursery at Gold Creek Road, Brookfield, provides 12,000 to 15,000 native plants annually, all propagated by volunteers during their fortnightly nursery days. These native plants then go back into the catchment, helping to provide habitat, bank stabilisation, connectivity, shade and natural beauty to the catchment.
The group also hosts various community events, including educational talks and a quarterly newsletter. A highlight of the year is the Kids Day at The Cottage, where since 2010, hundreds of kids from the catchment and western suburbs of Brisbane gather at The MCCG Environmental Centre, which engages hundreds of children in hands-on environmental activities such as plant potting, wildlife shows, and invertebrate displays. MCCG also runs an annual platypus survey, held each September, where volunteers observe 10–15 platypuses across Moggill and Gold Creeks, making the catchment one of Brisbane’s strongholds for this species.
Through its extensive volunteer efforts, MCCG has made a significant impact on restoring the catchment while inspiring future generations to continue protecting the environment
