Helensburgh is not renowned for climate activism. A coalmining town, Helensburgh was established around the Metropolitan colliery, Australia's oldest continually operating coal mine, in the 1880s.
The coal transnational Peabody Energy, which owns the Metropolitan, sponsors local activities such as school sporting teams and community fairs.
However, 35 people attended a climate-focused public meeting in the NSW south coast town on November 2.
