The bioregion of Australia, New Zealand, Antarctica and New Guinea possesses a unique natural heritage stretching back over 50 million years since the break-up of the great southern continent of Gondwana. The South Australian Museum focuses on enhancing a general knowledge of this extraordinary legacy by encouraging photography of the region's nature and wilderness, and promoting an annual competition to find the Nature and Landscape Photographer of the Year. Australasian Nature Photography: ANZANG Sixth Collection presents more than 150 of the finest photographs submitted to the competition. Each photograph is accompanied by technical information as well as anecdotes about how the picture was taken, which will stimulate yet further interest in the flora and fauna and their conservation in the region. Nick Moir from New South Wales is the Overall Winner for the 2009 ANZANG Nature Photography Competition with his evocative image Temora bushfire. Prizes were awarded in 11 other categories, including the Portfolio Prize for the photographer who submits the best of six or more images. This year, the Portfolio Prize winner is Justin Gilligan from New South Wales.
