“A very delicate person, beneath the flamboyance”. Jasper, Ladbroke Grove, 1977. “In the 1970s, Australia was rather cut off. I’d always wanted to live abroad, so I moved to Rome and then London. I was an art historian, but started studying photography part-time. I was interested in the demi-monde culture and began mixing in all sorts of circles. Jasper was a rather wonderful character...”.

Winner, photojournalism. Elephant in the room, by Adam Oswell, Australia Zoo. Visitors watch a young elephant performing underwater.

Close Encounter of the Insect Kind: “Check out the awesome face on this praying mantis. I can't get over the mouth, it's like something from a science fiction movie. Of all photographic styles macro is definitely my favorite. I am constantly amazed, in every photo that I take, by the intricate level of detail that exists on even the smallest of creatures. It's a stark reminder that a very complex and infinitely beautiful world exists just beyond our human-sized level of perception. Photo taken in Donnybrook, Queensland, Australia” – Andrew Young.
