Gabrielle Wang's great-grandfather travelled to the Victorian goldfields from China in 1853. Wang grew up in Melbourne, where she studied graphic design at RMIT. She later worked as a graphic designer, and studied Chinese at Melbourne University. Keen to learn more about her Chinese heritage, Wang lived in Taiwan for five years, and then lived for a time in China. She studied painting in both countries.
She returned to Australia and taught Chinese at Homesglen TAFE, at the same time enrolling in a TAFE course about writing for children. It was this course that led Wang to produce her first book, The Garden of Empress Cassia. It won the 2002 Aurealis Award (children's division - best long fiction) and was listed on the international USBBY Outstanding International Books List in 2012.
Since then, Wang has published a range of works for younger readers, including the series Poppy (for Our Australian Girl) and Pearlie, and standalone works including A Ghost in My Suitcase (for which she won a second Aurealis Award) and The Beast of Hushing Wood. In 2018, her work Ting Ting the Ghosthunter was a finalised for the Aurelis Awards, Best Children's Long Fiction category.
From 2022-2023 Gabrielle held the prestigious position of Australian Children's Laureate.
