Born in Scotland in 1943, Allan Baillie moved to country Victoria with his family at the age of seven. He lived in various Victorian country towns before spending the final years of his school life in Melbourne, attending Brighton High School. Baillie started writing when he was at school and in 1961 joined the Melbourne Sun as a cadet journalist while studying journalism at the University of Melbourne. He subsequently worked for the Telegraph, the ABC and the Australian Women's Weekly during his career as a journalist.
In the late 1960s Baillie travelled extensively in Asia while working on various journalistic assignments. These experiences, particularly those in Cambodia, inspired his book Little Brother (1985), which dealt with two brothers separated during the civil war in that country. His book Rebel! (1993) based on a true story, is set in Burma. His visit to China in 1989 coincided with the student massacres at Tiananmen Square and he wrote several books as a result of these experiences, including The China Coin (1991) and Bawshou Rescues the Sun (1991).
Baillie's first children's book, Adrift, appeared in 1983, and others for young people followed, including Riverman (1986) and Eagle Island (1987). In 1989, Baillie had the distinction of having two books shortlisted for the Children's Book Council of Australia's Book of the Year awards: Megan's Star (1988) and Drac and the Gremlin (1988). His only novel for adults, Mask Maker, was published in 1974.
Since 1987, Baillie has been a full-time author and has written many successful, award-winning novels and picture books for children, many of which have been published overseas and translated into several languages. These include Old Magic (1996) and Dragonquest (1996). His short stories have appeared in several anthologies including Dreamtime (1989), Mates (1989), and Bizarre (1990).
Baillie's award wins include the New South Wales Premier's History Prize (Young People's History), the Patricia Wrightson Prize for Children's Books, the Children's Book Council Book of the Year Award, the Australian Multicultural Children's Literature Awards, and the inaugural Kathleen Fidler Award. He also been shortlisted for many more.
