There has been a massive public campaign against the supertrawler led by Greenpeace, rec fishing groups in Tasmania, Victoria and South Australia. Check out the website: http://stopthetrawler.net/
They have petitioned the Federal Fisheries Minister Joe Ludwig. The pressure has led to Environment Minister Tony Burke implementing a number of restrictions on the supertrawler's operation (but not enough to stop it - yet!). Labor backbencher Melissa Parke is putting up a private member's bill this week to ban the supertrawler with support from the Greens.
The Libs are basically supporting the supertrawler, although at least Wilson Tuckey has questioned the logic of this ship strip-mining our pelagic fishery.
Get onto Twitter, Facebook and join the protest against the supertrawler - the more voices the more chance of getting the powers that be to ban the thing (don't hold out on the Libs doing anything - it's been the Greens who've pushed to get this bloody thing banned against Labor and Liberal support for the venture!).
