He was a member of the New South Wales Legislative Assembly representing the electoral district of Newcastle for the Liberal Party of Australia from the 2011 New South Wales state election until 6 August 2014 when he moved to the parliamentary crossbench and sat as an independent after the Independent Commission Against Corruption heard evidence that Owen may have breached electoral funding laws.

Document 4: David Titley: David William Titley is a professor of meteorology at Pennsylvania State University and the founding director of their Center for Solutions to Weather and Climate Risk. He was also NOAA's chief operating officer from 2012–2013. Before assuming these positions, he was a rear admiral in, and the chief oceanographer of, the U.S. Navy, in which he served for 32 years. Titley initiated the Navy's Task Force on Climate Change, and serves on the CNA Corporation's Military Advisory Board. He was formerly a climate change skeptic, but later changed his mind after looking at the evidence of what factors influence climate–which are, according to Titley, "what are the larger things doing – what is the ocean doing? What is the sun doing? And what's our atmosphere doing?" Since then, he has described climate change as "one of the driving forces in the 21st century" and said that it contributed to the 2011 Arab Spring.
Document 5: Wallaby: A wallaby is a small- or mid-sized macropod found in Australia and New Guinea. They belong to the same taxonomic family as kangaroos and sometimes the same genus, but kangaroos are specifically categorised into the six largest species of the family.

Document 7: Cry of the Kalahari: Cry of the Kalahari (1984) is an autobiographical book detailing two young American zoologists, Mark and Delia Owens, and their experience studying wildlife in the Kalahari desert in Botswana in the mid-1970s. There they lived and worked for seven years in an unexplored area named Deception Valley in the Central Kalahari Game Reserve. With no roads and no people and the nearest civilization eight hours away they had only each other and the animals they studied as company, most of which had never seen humans before. Their research focused mainly on lions, brown hyenas, jackals and other African carnivores. "Cry of the Kalahari" is the personal story of the Owens' encounters with these and a myriad of other animals and depicts their own struggle to live and work in such an inhospitable and unforgiving environment.
Document 8: Macropidia: Macropidia fuliginosa, the sole species of genus Macropidia, is a perennial rhizomatous flowering plant. Commonly known as the black kangaroo paw, it is endemic to Southwest Australia, specifically from Perth to Geraldton in the north of the region.
Document 9: Rabbit: Rabbits are small mammals in the family Leporidae of the order Lagomorpha, found in several parts of the world. There are eight different genera in the family classified as rabbits, including the European rabbit ("Oryctolagus cuniculus"), cottontail rabbits (genus "Sylvilagus"; 13 species), and the Amami rabbit ("Pentalagus furnessi", an endangered species on Amami Ōshima, Japan). There are many other species of rabbit, and these, along with pikas and hares, make up the order Lagomorpha. The male is called a "buck" and the female is a "doe"; a young rabbit is a "kitten" or "kit".

Document 13: Emu: The emu ("Dromaius novaehollandiae") is the second-largest living bird by height, after its ratite relative, the ostrich. It is endemic to Australia where it is the largest native bird and the only extant member of the genus "Dromaius". The emu's range covers most of mainland Australia, but the Tasmanian emu and King Island emu subspecies became extinct after the European settlement of Australia in 1788. The bird is sufficiently common for it to be rated as a least-concern species by the International Union for Conservation of Nature.
Document 14: Cane toads in Australia: The cane toad in Australia is regarded as an exemplary case of a "feral species"—others being rabbits, foxes, cats, dogs and giant mimosa. Australia's relative isolation prior to European colonisation and the industrial revolution—both of which dramatically increased traffic and importation of novel species—allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the species subsequently introduced. The recent, sudden inundation of foreign species has led to severe breakdowns in Australian ecology, after overwhelming proliferation of a number of introduced species for which the continent has no efficient natural predator or parasite, and which displace native species—in some cases these species are physically destructive to habitat as well. Cane toads have been very successful as an invasive species, having become established in more than 15 countries within the past 150 years. In the Environment Protection and Biodiversity Conservation Act 1999, the Australian Government listed the impacts of the cane toad as a "key threatening process".
Document 15: Tim Flannery: Timothy Fridtjof "Tim" Flannery (born 28 January 1956) is an Australian mammalogist, palaeontologist, environmentalist and global warming activist.
