South Australian Opposition Leader Steven Marshall says he wouldn't change a single thing about the Liberals' campaign for the state election.
Mr Marshall is feeling relaxed and confident and believes there will be a result by the close of counting on Saturday.
"I'm feeling good actually. It's been a great campaign," he told reporters at a polling booth in his own seat of Dunstan.
"I've enjoyed every second of this campaign, and overall I think the people of South Australia will make a solid decision."
Mr Marshall described the entrance of Nick Xenophon into the election as "interference", but welcomed anyone standing for parliament.
"The more people that run the better," he said.
The party leader said he was more than happy with the message the Liberals had put to the people, and wouldn't change a thing.
"I've loved it. I've absolutely loved the campaign that we've run," he said.
"I love our policy agenda that we've put forward. It's positive. It's not a crazy spending spree that Labor have put out."
Mr Marshall's comments came as a late opinion poll pointed to a Liberal victory, with support for Mr 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.
The opposition leader said the outcome was still in the balance, but he was confident voters would know the outcome on Saturday.
"I've got a feeling that we will," he said.
