South Australia has done it and there are no dramas. I run a volunteer rubbish collecting group and we’re constantly collecting these dreaded things (out of culverts, trees, bushes – everywhere). If you want to collect rubbish whilst going for a walk on the beach you only have to pick up one of these water filled baddies out of the ocean to start putting the rubbish in! How about doing something about a container deposit too – we’re decades behind :-(
