‘An amphitheatre of pandani watch on as the galactic core, swathed in airglow, rises over an alpine lake, nestled in a rugged Tassie mountain range. Lady Aurora dances under the Magellanic Clouds. This image was captured on a crisp night in one of Tasmania’s more rugged and majestic multi-day walks.’ Loinnekumme country, South-west national park, Tasmania.

‘This is not a dead leaf; it is a result of massive tides retreating over mudflats. I thought of a dead tree and a bird as we flew over the flats in the chopper. As this blacknecked stork flew towards the drainage, we banked hard just in time to capture them together.’ Balanggarra land, Wyndham, Western Australia.
