4 Australian States and Territories have banned high-density polyethylene (HDPE) plastic bags. Tasmania banned HDPE bags on May 29, 2013 after South Australia had already banned the bags in May 2009, the Northern Territory in September 2011 and the Australian Capital Territory (ACT) in November 2011.
The Tasmanian ban applies to non-biodegradable, lightweight HDPE bags less than 35 µm thick. The ban will come into force in November 2013. Biodegradable bags continue to be allowed under the ban.
