The 2026 CBCA Book Week theme is "Symphony of Stories," and Book Week runs from Saturday 22 to Friday 28 August 2026. The theme celebrates the idea that stories, like music, bring people together, note by note and page by page. For your child's costume it means one simple thing: dress as a favourite book character. Characters with a musical or storytelling streak fit the theme beautifully, but any beloved book character is welcome. Below we explain the theme in plain English, then give you kids' costume ideas you can sort today.

What is the 2026 Book Week theme?
The 2026 Children's Book Council of Australia (CBCA) Book Week theme is "Symphony of Stories." A symphony is many different instruments playing together to make one piece of music, and the theme uses that image for reading: every book is a different voice, and together they make something bigger. Schools and libraries use it to celebrate the joy of sharing stories, the way stories connect us, and the many "instruments" of storytelling, from picture books to poetry to song. You can read the official theme announcement on the CBCA website.
For families, the theme is a gentle guide, not a strict rule. Your school may lean into music and instruments for decorations and activities, but for the dress-up day the tried-and-true brief still stands: come as a character from a book you love.
When is Book Week 2026 in Australia?
Book Week 2026 runs from Saturday 22 August to Friday 28 August. Most schools hold their costume parade or dress-up day during that week, often on the Wednesday, Thursday or Friday, though the exact day is set by each school. Check your school newsletter for the date, and if the parade lands early in the week, give yourself a weekend of lead time to get the costume sorted. With Book Week only a couple of weeks away, the popular kids' sizes tend to sell out first, so it pays to lock yours in early.
What does "Symphony of Stories" mean for costumes?
In practice, "Symphony of Stories" opens up three easy paths for a costume:
- A character who sings, plays or performs. Think Mary Poppins, the Pied Piper, or a character from a musical picture book. These tie directly to the "symphony" idea.
- A classic storybook character. Fairy-tale royalty, wizards and witches, brave adventurers. Instantly recognisable and always in the spirit of Book Week.
- A character your child genuinely loves. The best costume is one your child will happily wear all day. Enthusiasm reads better than accuracy in any parade.
The golden rule for schools: the character should come from a book. If you can point to the title it appears in, you are on safe ground.
Best costume ideas for kids (that fit the theme)
Here are four easy, recognisable options, each drawn from a well-loved book and each ready to wear straight out of the pack. They are ordered from most on-theme to most adventurous.
1. Mary Poppins (practically perfect, and on-theme)
Mary Poppins is the ideal 2026 pick: she is a much-loved book character (P.L. Travers first published her in 1934) and she sings, which lands squarely on the "Symphony of Stories" theme. A tidy nanny outfit, an umbrella and a carpet bag, and your child is set. It works just as well for teachers who want a polished, no-fuss look.
A neat, ready-to-wear nanny outfit. Add an umbrella and a carpet bag for the full spoonful-of-sugar effect. An adult size is available for teachers too.
2. Fairy-tale princess (storybook royalty)
Fairy-tale princesses appear across dozens of books, from classic Brothers Grimm tales to modern picture books like The Paper Bag Princess. It is a reliable favourite for younger children, and a costume that gets worn well beyond Book Week for parties and dress-ups.
A flowing storybook gown that suits countless fairy-tale characters. Pair with a princess wig or a simple tiara to finish the look.
3. Wizard or witch (Harry Potter, Room on the Broom and more)
A hooded cloak is one of the most versatile pieces you can own. With a wand it becomes a young wizard from Hogwarts; with a broom it is the witch from Julia Donaldson's Room on the Broom; add a pointed hat and it suits The Worst Witch. One item, many books, which makes it brilliant value.
The one piece that covers several books at once. Add a wand for a wizard or a hat and broom for a witch. Great for siblings sharing a theme.
4. Viking adventurer (How to Train Your Dragon)
If your child rolls their eyes at "dressing up," a Viking usually wins them over. Hiccup and the Vikings of Berk began as Cressida Cowell's How to Train Your Dragon books, so it is a genuine book character with plenty of action-hero appeal. It is also one of our most affordable complete costumes.
A complete top, trousers and hat in one pack. Add a toy shield and you have an instant Berk-ready adventurer.

How to pull a costume together fast
Two weeks is plenty of time if you keep it simple. A few tips that save stress on parade morning:
- Start with one hero piece. A cloak, a gown or a complete costume pack does most of the work. Accessories are the finishing touch, not the foundation.
- Bring the book. Sending the actual book to school makes the character unmistakable and ticks the "from a book" box for teachers.
- Pick comfort. Your child wears this for hours, so choose something they can sit, play and eat lunch in.
- Order early. Popular kids' sizes go first in the fortnight before Book Week. Locking it in now beats a last-minute scramble.

Frequently asked questions
What is the Book Week 2026 theme?
The 2026 CBCA Book Week theme is "Symphony of Stories." It celebrates the way many different books, like many instruments in an orchestra, come together to create something greater than any single voice.
When is Book Week 2026 in Australia?
Book Week 2026 runs from Saturday 22 August to Friday 28 August. Individual schools choose their own dress-up or parade day within that week, so check your school's newsletter for the exact date.
Does my child's costume have to match the "Symphony of Stories" theme?
No. The theme guides the week's activities, but the dress-up brief is simply to come as a character from a book. Characters who sing or perform, such as Mary Poppins, are a lovely nod to the theme, but any book character is welcome.
What are some easy Book Week costumes for kids?
The easiest options are complete, ready-to-wear costumes based on a recognisable book character: Mary Poppins, a fairy-tale princess, a wizard or witch with a hooded cloak, or a Viking from How to Train Your Dragon. Each needs only one or two accessories to finish.
How early should I buy a Book Week costume?
Buy as early as you can. Popular children's sizes tend to sell out in the two weeks before Book Week, so ordering ahead gives you the best choice and avoids a last-minute rush.
