No music, no voices, just the sound of a valley halfway up a Tasmanian mountain. This soundscape is full of birds and breeze echoing backwards and forwards across a reservoir. Kunyani is swirled with mist and the city of Hobart spreads below, in miniature, on a still, early morning. We’re halfway up the mountain, at the Hobart Waterworks Reserve where two huge reservoirs store water for use by the populace below. The deep valley where the reservoirs are situated means there is an echoey, dream-like quality to all the sound. You can hear a unique mix of forest and water birds at this place every single morning. There were tawny frogmouths coming as I trudged up the hill, and as I was sitting listening to the day unfold a scarlet robin danced on the edge of the bush — feeding, patrolling and, just maybe, calling for the microphone.
