As Australians cast their ballots in a tight election Saturday afternoon, Sen. Nick Xenophon worked up a sweat while preparing kebabs at a Greek restaurant in his hometown.

"Nick, if you no get across the line tonight, I give you a job," owner Yianni Tsagariolis shouted in a thick Greek accent, drawing laughter from Xenophon supporters who had gathered at the restaurant.

But with early results showing the Nick Xenophon Team (NXT) party winning between three and five Senate seats, it became clear the restaurant's charcoal grill was the only reason for Australia's next political kingmaker to break into a sweat.
