The Nick Xenophon Team says South Australians are smart enough to make their own judgment on negative attacks by the major parties.
Senator Xenophon's fledgling group on Friday drew sixth spot on South Australia's Senate ballot paper, with Labor in second place, the Greens fourth and the Liberals eighth.
