Hi there. I am the trails coordinator for Cotter Pines and Zoo Pines in Canberra, and I note that a number of trails and trail links are absent from your map for Cotter Pines. They are updated on Trailforks. 
1. Cosmic Girl - on the LHS of 13 Acres Track
2. Link tracks (2) off 13 Acres track to The Spine 
3. Link tracks from The Spine to Start Me Up and Dazed and Confused Trails.
4. Extension to Sneaky Pete Track
Are you able to update your record please?
