Mark Parnell

Parnell was a founding member of the South Australian Greens and, prior to being elected, was a solicitor with the Environmental Defender's Office, a free community legal centre specialising in public interest environmental law. In ten years with the Environmental Defenders Office, Mark helped many hundreds of clients on a wide range of state and national planning, pollution, biodiversity or resource matters. In 1999, he successfully represented the Conservation Council of South Australia in the State's longest ever environment trial, over tuna feedlots in Louth Bay. He also represented the Whyalla Red Dust Action Group Inc in its long-running campaign for environmental justice over OneSteel (formerly BHP) dust emissions from the Whyalla Steelworks.

Prior to his 10 years with the Environmental Defenders Office, Parnell was a campaign co-ordinator with The Wilderness Society (2 years) and the Australian Conservation Foundation (4 years). Parnell also spent 4 years working as a solicitor in private practice in country Victoria in the mid-1980s.

On 8 May 2008 Parnell delivered a record-breaking filibuster of more than 8 hours in the Legislative Council. His speech, and that of No Pokies MLC Ann Bressington which followed, were designed to highlight the lack of opposition by either major party to a bill changing the workers compensation scheme known as WorkCover. Parnell denied his speech deserved the label of "filibuster" as he considered himself and Bressington responsible for presenting the entire opposing case. See: 2008 Parnell–Bressington filibuster

In February 2011 Parnell condemned recent policy decisions by the state Labor government such as approval of the Mount Barker redevelopment and the renewal of the uranium exploration company Marathon Resources' right to drill in Arkaroola sanctuary. He said "The left-right stuff doesn't really work for me anymore, there's fewer and fewer things to distinguish them [and] members are carefully watching the performance of the major parties".[1]
