Early life

Andy was born and raised in Melbourne, Australia. He attended Pascoe Vale Primary School, Eastmont Primary School and later, Yarra Valley Grammar School.Inspired by his love of reading he wrote and drew short stories and cartoons for his family and friends. In the fifth grade he purchased a typewriter at a second-hand stall at school and created his own humour magazine called ‘Popcorn’, which he sold for three cents a copy. In high school he began writing for the school's magazine and, inspired by punk/new wave music, wrote satirical songs and formed a band with his friends.

Career

After graduating high school in 1979, he attended Monash University where he completed a BA with honours in English Literature, while at the same time gaining writing and performing experience as the front man for a number of experimental bands in Melbourne’s vibrant alternative music scene centred around the Crystal Ballroom.

After completing a Diploma of Education at Rusden Teachers College (now Deakin University) in 1987, Andy became a high school teacher.

It was during this time as a teacher that Andy began to write and self-publish collections of outlandish stories and cartoons in an attempt to inspire his students to embrace the fun and limitless possibilities of creative reading and writing.

He eventually took leave from his job in 1991 and enrolled in a full-time Diploma of Professional Writing at Deakin University. It was during this period that he met and formed a partnership with like-minded illustrator Terry Denton.

Advocacy

Andy is the Australian Children’s Laureate 2026-2027. He is an ambassador for The Indigenous Literacy Foundation and the Pyjama Foundation, and was awarded the Dromkeen Medal in 2015 to honour his outstanding contribution to Australian children’s literature.
