Similar to the law in South Australia, the Northern Territory and the ACT, it appears that the Tasmanian state government will also follow suit in implementing restrictions on certain kinds of plastic bags.  The date in which the legislation comes into force is not yet confirmed, but appears to be around late 2013.  Despite contradictory evidence as to their effectiveness, plastic bag bans are a popular legislative option for a government to “appear green.”
