During the 2013 federal election, Xenophon nominated four key policy issues; gaming machine reforms, stopping palm oil from being sold in Australia, breaking up the supermarket duopoly, and better deals for Riverland irrigators in the Murray-Darling basin rescue plan. Xenophon's voting result increased to 24.9 percent, a few percent short of two quotas. A record number of candidates stood at the election. Group voting tickets came under scrutiny because multiple candidates were provisionally elected with the vast majority of their 14.3 percent quotas coming from the preferences of other parties across the political spectrum.
