Earlier this year for Keep Australia Beautiful week, a little stunt was performed to remind people of the intrinsic link between our cities storm water drains and our oceans and beautiful waterways.

What people don't know is that any litter dropped on the street, will inevitably end up going down a storm water drain and will eventually reach the ocean.

Sound systems were installed in storm water drains in both Sydney and Brisbane with sounds of the ocean (whale calls, dolphin noises, waves, seagulls, etc.) echoing out of the drains and a simple message, "What goes in here, comes out in the ocean, put your rubbish in the bin and keep Australia beautiful".

Needless to say, there were some very inquisitive reactions!

Dispose of your litter thoughtfully. www.kab.org.au
