The polls have Labor in front, but Saturday's South Australian election is far from a done deal as the Liberals bid to defy the pundits and retain power.
After governing for 16 of the past 20 years, Labor needs to pick up at least five seats to end the one-term government of Premier Steven Marshall.
It can do that with a swing of a little more than two per cent, but questions remain over whether the swing will come in the right places.
A shift to pre-poll and postal ballots has also muddied the waters.
Among SA's 1.2 million registered voters, more than 170,000 have cast an early ballot while another 133,000 have applied for a postal vote.
Several thousand more will vote by post after testing positive for COVID-19 or being forced into isolation late this week as close contacts.
There's also six independents vying for re-election, including three who left the Liberal Party to sit on the crossbench.
Their fate could be crucial to the final result, with government potentially going to whichever of the major parties can successfully broker a deal for minority rule.
Opposition Leader Peter Malinauskas has focused heavily on health throughout the election campaign, promising to spend big to fix an ailing system plagued by ambulance ramping and overloaded hospitals.
But that has allowed Mr Marshall and his team to mount a sustained attack on Labor's big spending promises, warning of higher taxes and charges if the opposition wins.
Both leaders were back on the streets on Friday in a final pitch for votes.
Despite trailing in opinion polls, the premier said he believed the government could win.
"The people of SA know that under a Liberal government you are always going to have a stronger economy, stronger finances, and that is good for families," he said.
Mr Malinauskas gathered with hospital and ambulance staff as he declared "this election is a health election".
"This election is an opportunity to get our health system back on track with a considered plan, a fully funded plan," he said.
If the government falls, it will be the first in Australia to suffer such a fate during the COVID-19 pandemic.
Though it's unclear just how much SA's handling of the virus will sway voters.
The state did well in the early stages of the pandemic but the government later came in for criticism, at times for maintaining local restrictions, and then for opening SA's borders as the Omicron wave hit.
The polls open at 8am on Saturday and close at 6pm, with the SA Electoral Commission warning a result may not be known for several days.
