Set up as stations in the library meeting room and children's section. I found a lot of inspiration on librarian Facebook groups as well as the official website. Here are the stations:
Grannies Photo Booth
Zoo
Bus
Keepy Uppy
Coloring
Bluey or Bingo Headbands
Long Dog Scavenger Hunt
Gnomes Scavenger Hunt
Door Prize Drawing: Wooden Gnomes to Paint
Storytime: I read one story from Bluey Awesome Storybook Collection (Mum School, The Pool, Grannies, Bob Bilby, Charades, and Camping).
Both the storytime and random door prize drawing took place about 30 minutes into the 1 hour event.
