South Australian Premier Jay Weatherill says he is feeling "completely philosophical" about the state election he hopes will deliver a record fifth term for Labor.
Mr Weatherill said he wasn't nervous after casting his vote at the Alberton Primary School - in his electorate of Cheltenham - on Saturday.
"When you do everything you can, you put your best foot forward, you tell your story, especially a story you're proud of, I'm just very philosophical about the result," he told reporters.
There was little fanfare as the premier cast his ballot in the school gym after a brief wait in line, nor a sausage sizzle outside to reward him for fulfilling his democratic duty.
But unlike Opposition Leader Steven Marshall, Mr Weatherill was not confident of a result by Saturday night, saying he didn't want to presume anything.

Whatever the outcome, he had no regrets about the campaign his party had run.
"We've put forward a very positive program and vision for the future," he said.
"It's now down to the people. I've done everything I can."
Mr Weatherill's comments came as a late opinion poll pointed to a Liberal victory with support for Nick Xenophon's SA-BEST party continuing to slide.
The Newspoll showed the Liberals leading the primary vote with 34 per cent support, compared to 31 per cent for Labor and just 17 per cent for SA-BEST.
