On 11 October 2007, Xenophon called a press conference at the Adelaide Zoo in front of the giraffe enclosure, declaring he would "stick his neck out for South Australia" by announcing his resignation from the South Australian Legislative Council in an attempt to gain election to the Australian Senate at the 2007 federal election. His platform consisted of anti-gambling and consumer protection measures, attention to the water crisis affecting the Murray River, ratifying Kyoto, opposition against a "decrease in state rights", and opposition to WorkChoices. Nick Minchin, a Liberal senator from South Australia, urged people not to vote for Xenophon. Due to running as an independent Xenophon's name did not appear above the line on the ticket, instead he was represented only by the letter "S" above the line, with voters having to search for his details.
