Thought this may interest some. The unmistakeable, very loud and persistent call of Litoria dentata was coming from the adjacent Mt Ainslie Nature Reserve last night. Not supposed to be found in Canberra as far as I know, but they are common on the south coast and could easily be transported here accidentally, which I would guess is how this one may have arrived.

Annoyingly I have been unable to find a call recording online, but if you have Ederic Slater’s ACT and se NSW frog calls CD or Dave Stewart’s CD Australian frog calls – subtropical east, it is on those.
Cheers
