Andy Griffiths

Andy Griffiths is a renowned Australian author, best known for his children's books. He has written numerous series, including the Treehouse series, the Just series, and the Schooling Around series. His work has been recognized globally, with several of his books becoming New York Times bestsellers.

Griffiths has a unique approach to writing for children, creating imaginative and engaging stories that have captivated young readers. His books have been adapted for stage and television and have won over 70 children's awards in Australia. His popularity is evident in the fact that there is probably not a child in Australia who has not heard about his Just! or Treehouse books.

Griffiths has had a successful collaboration with illustrator Terry Denton, with whom he has produced many best-selling books. Together, they have created the Just! series, the popular The Bad Book and The Very Bad Book, the ridiculous illustrated guide What Bumosaur is That?, and the Seussian-inspired early readers The Cat on the Mat is Flat and The Big Fat Cow that Goes Kapow! Their latest book is The 13-Storey Treehouse.

In addition to his writing, Griffiths is a passionate advocate for literacy. He has worked as a high-school teacher, been the lead singer in a rock band, and a stand-up comedian. He has two daughters and currently resides in Melbourne, Australia.
