NPA-ACT was founded in 1960 to advocate for a national park in the national capital. Accomplishing this objective required 24 years of energetic exploration and persistent lobbying. Namadgi National Park was established in the southern part of the ACT in 1984 and subsequently expanded to include nearly half of the ACT. Hence, the NPA-ACT has a strong interest in protecting the NNP from degradation and exploitation. We are particularly concerned with preventing the invasion by weed and feral species and with a continuing high standard in management practices.

Our conservation program includes a large number of work parties assisting Park Rangers with weed removal and replanting of native species. There are also work parties to stabilise and/or refurbish historic structures and occasionally to remove unnecessary fencing. Non-members may join these work parties by contacting the leader listed in the program.
