A New Zealand company is involved in an environmental awareness stunt at Australia's famous Bondi Beach.

A large poo-shaped plastic sculpture has been installed at the Sydney beach to highlight the amount of waste being dumped in the ocean.

The four-metre high piece represents the volume of plastic dumped in oceans every 30 seconds.

Better Packing Co co-founder Rebecca Percasky told Tim Dower that the theme of this World Environment Day is beat plastic pollution.
