Book Week 2021 runs from 21st – 27th August and each year there is a different theme for Australian Book Week. This year, the theme is “Old Worlds, New Worlds, Other Worlds”.

Book week is a fantastic opportunity for your child to celebrate their favourite characters from their favourite books by dressing up. This year’s theme is a great chance for your child to be anything they want to be, let their imagination (and yours) take you to another world of creativity!

Some of us aren’t as crafty as others, so if you need a little inspiration, then we’ve got some great Book Week Costume Ideas below.
