A light hearted approach to the teaching of the "birds and the bees" is among an impressive shortlist of information books vying for the Children's Book Council of Australia Book of the Year Awards.
The modern resource guide was put together by the Australian cartoonist Fiona Katauskas to explain the facts of life to her son, and looks at everything from caesarean birth to sperm and egg donation and IVF technology.
Katauskas's The Amazing True Story of How Babies Are Made is up against We Are the Rebels, Clare Wright's abridged version for teenagers of her 2014 Stella Prize-winning study of the women of the Eureka Stockade rebellion.
Invertebrate zoo keeper Rohan Cleave's shortlisted children's book, Saving the Lord Howe Stick Insect, was also among 52 books entered for the Eve Pownall Award for Information Books, and one of 402 books entered overall.
Illustrated by Carol Tulloch, it tells the remarkable conservation story of the Lord Howe Island stick insect brought back from the brink of extinction by a unique captive breeding at Melbourne Zoo.
Margaret Hamilton, deputy chairman of the Children's Book Council, said writing across the four fiction categories was very strong and testament to the calibre of books for young readers and the skill of authors.
"Picture books and early childhood are also strong categories, with a wide variety of books ranging from laugh out loud humour to poignant stories about refugees," she said.
The CBCA Book of The Year Awards celebrates its 70th anniversary this year making it the longest running book awards in Australia, and is regarded by librarians, booksellers and parents as a buying guide to quality Australian children's writing.
The shortlist for Book of the Year for Older Readers includes Fiona Wood's Cloudwish, John Larkin's The Pause and Erin Gough's The Flywheel. For younger readers, the works by veteran writers dominate including Morris Gleitzman's Soon, book five in a sombre series about a Jewish boy struggling to survive after the liberation of Poland at the end of World War II.
Libby Gleeson and Freya Blackwood have been nominated for The Cleo Stories, A Friend and A Pet, Sally Morgan for Sister Heart and Emily Rodda for Shadows of the Masters.
Picture book of the year features James Foley's hilarious illustrations of a zombie rabbit, in My Dead Bunny, and Bruce Whatley's illuminations of the lyrics to And the Band Played Waltzing Matilda, Eric Bogle's anti war song about the Battle of Gallipoli.
