Osmar Egmont Dorkin White (2 April 1909 – 16 May 1991) was an Australian journalist, war correspondent and writer. He is most famous for his vivid description of the New Guinea Campaign during World War II. He also wrote under the pseudonyms Robert Dentry, EM Dorkin, and Maros Gray.
Born in Feilding, New Zealand, White moved with his family to Australia at age five and spent his childhood in Katoomba.
He began his career as a journalist with the Cumberland Times in Parramatta, New South Wales, before moving to the Wagga Wagga Advertiser. He also wrote for the Sydney Daily Telegraph as a district correspondent while studying at the University of Sydney. From 1928 to 1933, he worked as a freelance writer in South and Southeast Asia and Papua New Guinea and published dozens of short stories in The Australian Journal, The Bulletin and magazines in the United Kingdom.
White was a journalist with The Herald and Weekly Times during the Japanese invasion of Papua New Guinea in 1942, before becoming an accredited war correspondent with the Australian forces there. Together with Australian war photographer Damien Parer and war correspondent Chester Wilmot, White walked over the Bulldog Track to cover the guerrilla campaign conducted by Kanga Force and later also covered the Kokoda Track Campaign, detailing the trials and triumphs of Allied troops during that time. He was seriously wounded during the New Georgia campaign and, while recovering in Australia, he wrote Green Armour, which described in detail the harsh conditions of the jungle fighting in 1942 including on the Kokoda Track.
