National Water Week 2025

2025 poster competition theme: Water Heroes: Save Every Drop

This years theme highlights the importance of protecting our water resources by saving every drop.

As our climate becomes hotter and drier, and demand for water increases, it’s more important than ever to use water wisely.

This years theme encourages students to see themselves as everyday heroes — people who make small, positive choices that add up to big impacts. Whether it’s turning off the tap, having short showers, or spreading awareness, every action helps.

By becoming Water Heroes, students can lead by example and inspire their families, schools, and communities to value and conserve every drop.

Your mission is to create a poster that inspires our community to reduce their use and help save our precious water resources. Remember, every little drop counts! 

Entries for the 2024 poster competition are now open!

To celebrate National Water Week, children from kinder to Grade 6 are encouraged to design, draw or paint an A3 poster that demonstrates how we can all be Water Heroes, saving water at home, in the garden and at school!

Tips for uploading a poster

  • Please ensure only high resolution, high quality images are submitted
  • Image files must be in .JPG, .PDF or .PNG formats only
  • Uploaded files are limited to 20MB
  • Original posters can either be scanned or photographed
  • Remember if taking a photo, please ensure a clear, non-blurred image is taken.  Keep these tips in mind:
    • ensure good lighting to avoid shadows
    • make sure the poster fills the entire screen – an overhead shot, taken directly above the poster, is often the best option
    • ensure the photo matches the orientation of the poster – if the poster is in landscape format, take the photo horizontally. If it’s in portrait format, take the photo vertically
    • avoid using flash, as it can cause glare

Educator’s guide and activities: Inspire your students to become water heroes

To help introduce this year’s National Water Week theme to children/students, we’ve created an Educator’s Guide. Designed to support learning in both early childhood and primary classrooms, this resource includes background information, discussion prompts, and activity ideas — all aligned with the 2025 theme, Water Heroes: Save Every Drop.

Whether you’re kicking off a water unit or supporting students in creating their posters, these resources will make it easy to bring the message of water conservation into your classroom in a fun, engaging and meaningful way.
