National Water Week aims to raise public awareness and improve understanding of water issues in Australia.
It is the only event in Australia that provides a national focus for water issues.
The theme for this year's National Water Week is "Healthy Catchments, Healthy Communities".
This poster was submitted in the 2011 poster competition by Grade 3 student Ella Rose of Kardinia International College.
To celebrate National Water Week, once again hosted our annual poster competition.
