Key findings
- "Book week costumes" is searched 18,100 times a month in Australia (Semrush AU database) — the biggest single dress-up search term of the mid-year calendar.
- Australians leave it late: "easy book week costumes" draws 1,600 monthly searches, and "book week costume ideas" another 2,900 — parents are hunting for fast solutions, not sewing patterns.
- Couples dressing is a defining Halloween behaviour: "couples halloween costumes" and "costumes for couples for halloween" draw 2,400 monthly searches each.
- Oktoberfest demand is led by women: "dirndl" (2,900/month) out-searches "lederhosen outfit" (590/month) nearly five to one.
- Masquerade is Australia's quiet year-round dress-up niche: "masquerade" (8,100), "masquerade masks" (5,400), "ballroom mask" (3,600) and "masquerade mask" (2,900) add up to roughly 20,000 monthly searches with no single seasonal peak.
- Brisbane out-searches Sydney for costume shopping: "costume shop brisbane" (2,400/month) leads "costume shop sydney" (1,900/month).
Book Week: the biggest dress-up moment of the Australian school year
CBCA Book Week 2026 runs 22–28 August under the theme "Symphony of Stories". Search demand around it dwarfs every other mid-year occasion: the head term "book week costumes" alone records 18,100 monthly Australian searches, with "book week theme" (1,600), "book week costume ideas" (2,900) and "easy book week costumes" (1,600) rounding out the cluster. The prominence of "easy" and "ideas" queries points to a consistent pattern we also see in store: families decide late and need outfits that arrive fast. For context on what school families are choosing, see our Book Week costumes range.
Halloween: couples lead the search behaviour
Beyond the generic head terms (e.g. "halloween and costume", 6,600/month), the standout behavioural signal is pairs: two separate couples-focused phrases each draw 2,400 monthly searches. Group and duo dressing has become the organising principle of Australian Halloween parties — a shift retailers see reflected in Halloween costume baskets that contain two matched outfits.
Oktoberfest: a women-led season
"Oktoberfest outfit" records 4,400 monthly Australian searches, and the gender split is decisive: "dirndl" (2,900) versus "lederhosen outfit" (590). Australian Oktoberfest events are booming from Brisbane to Melbourne, and the data says women are planning outfits earlier and in greater numbers. Range context: Oktoberfest costumes.
The year-round undercurrents
Three clusters keep ticking outside the big seasonal peaks. Masquerade adds up to roughly 20,000 monthly searches across four phrases. Distinctly Australian dress-up culture shows in "aussie icons" (3,600), "australian icons" (2,900) and "aussie icons dress up" (1,300). And decades nostalgia holds steady — "costumes from 80s" draws 3,600 monthly searches, confirming decades dress-up as a standing category rather than a passing trend.
Where the demand lives
| Search term | Monthly AU searches |

Queensland punches above its weight: Brisbane plus Gold Coast plus state-level queries total 5,000 monthly searches, ahead of Sydney's combined 3,200.
