All photographs must be of natural fauna, flora or natural land/sky formations and must have been taken in the ANZANG bioregion.

ANZANG bioregion means Australia, New Zealand, Antarctica and the New Guinea region. The region of New Guinea is limited to the west by the Wallace Line (the bio-geographical line extending between Bali and Lombok northward through the Makassar Strait between Borneo and Sulawesi). To the east the New Guinea region includes the Bismarck and Solomon Archipelagos and islands of the South West Pacific, with its eastern boundary formed by the International Date Line. Note that for the purposes of this competition, our definition of the Wallace Line does not include Huxley’s modification, and therefore the islands of the Philippines are not included in our definition of the ANZANG bioregion. Antarctica includes the Sub-Antarctic Islands, which for the purposes of this competition are those south of the Antarctic Convergence or Antarctic Polar Front.

Entries in all sections are invited from photographers who use either digital or film cameras. Judges will consider the photographic technique plus the aesthetic, artistic and unique quality of all images when making their selections.
