What is Book Week?

Book Week is an Australian tradition, originating in 1945,  that celebrates Australian authors and illustrators that have an impact on children and young adults.

In schools and libraries across the country, children (and teachers) are invited to dress up as their favourite book character and partake in a range of activities aimed to highlight the importance and joy of reading.

Parents across the country are usually divided into two camps – those who love it and those who find it a nightmare trying to pull together a suitable book-related costume. Fear not … whether you love it or hate it, we’ve put together a list of Book Week costume ideas.


With the theme for Book Week 2021 being OLD WORLDS, NEW WORLDS, OTHER WORLDS encompasses a whole host of possibilities for a costume that fits the theme perfectly.

Does your child love fairytales and adventures? Maybe they prefer fighting dragons or sailing the seas. Or maybe it’s all about wizards or even space travel! You’ll have plenty of choice this year so think about what world most interests your child and start planning your costume now.

If your child is not sure about what to wear, we have some costumes ideas for you right here!
