Book Week 2025: Book an Adventure
Mark your calendars! Book Week 2025 will take place from August 16 to August 23, 2025, and the Children’s Book Council of Australia (CBCA) has announced this year’s theme: ‘Book an Adventure’.
The theme celebrates the magic of stories and their incredible power to transport us, whether across time, into fantastical lands, or deep into the minds of others. Every book is an adventure waiting to begin.
This year’s feature artist, Jess McGeachin, has beautifully captured this spirit with a whimsical map filled with imaginary characters and far-off places. His playful artwork invites children to dream, explore, and get lost in the wonder of reading.
2025 is also a milestone year, marking 80 years of Children’s Book Week. For eight decades, the CBCA has inspired generations of young readers, and Jess’ illustration is a joyful celebration of that legacy, reminding us all that every page turned is a new adventure begun.
