How to enter

It’s easier than ever to enter! Simply upload your posters to the new online portal.


  • Entries MUST be submitted via our dedicated NWW web portal (Please do not mail or drop off physical posters to the Westernport Water office)
  • Entries close at 5 pm Friday 1 September 2023.
  • Winners will be announced at school assemblies and on our website during National Water Week, 16-22 October 2023.

Tips for uploading a poster

  • Please ensure only high resolution, high quality images are submitted
  • Image files should be in .JPG, .PDF or .PNG formats
  • Uploaded files are limited to 20MB max
  • Original posters can either be scanned or photographed
  • Remember if taking a photo, please ensure a clear, non-blurred image is taken. Think about:
    • good lighting
    • ensuring the poster fills the entire screen, an overhead shot is often best as you are standing above the poster, looking down
    • avoiding flash, as if a glossy poster, you will get glare
