Any sighting of a Koala in the wild in the ACT is significant.

A spokesperson from the Two Thumbs Wildlife Trust has also written the following on their Facebook page: "I went out today (16 July 2026) with Brooke and 4 ACT Government Rangers to the tree the koala near Theodore was in. The tree was a Eucalyptus bridgesiana (Apple Box), a local koala preferred species of tree. I also managed to find some fresh koala pellets. The ACT Rangers took some koala pellets for DNA analysis etc and I took 6 koala pellets to the Australian National University and gave them to Dr Karen Ford who will do nutritional analysis and see what species of eucalyptus it has been feeding on etc." https://www.facebook.com/share/v/185vnXbzdh/
Vagrant koalas (i.e. isolated individuals not part of a known resident group) have been turning up in the Canberra area every few years since at least 1980. There was even one on Red Hill (in the late 1970s or early 1980s I think it was) which suggests they can be present and moving around between areas for some time before being reported.
