Voting is under way in the NSW election as the major parties' leaders make a desperate last-minute attempt to sway undecided voters.
More than 1.5 million people had already cast their ballots when early voting closed on Friday night, representing around 28 per cent of the state's 5.5 million voters.
Premier Dominic Perrottet is seeking a fourth consecutive four-year term for his Liberal-National coalition, while Labor leader Chris Minns is hoping to return his party to government after 12 years on the opposition benches.
Labor is the strong favourite to win the election, leading the polls and overwhelmingly ahead in betting agency odds.
But Mr Perrottet said the result was far from decided and he called on voters to back his party to grow the economy, create jobs and build vital infrastructure.
"It's a very important election and we know that there are a lot of undecided voters," he told Seven's Sunrise program on Saturday.
The premier voted in Beecroft in the morning, accompanied by his wife Helen and the couple's youngest daughter, Celeste, before heading south in a final push to bolster the Liberals' results in western Sydney.
Mr Minns, who will cast his ballot in his marginal seat of Kogarah later in the day, said Labor would fight for every vote until polls closed at 6pm.
"I still think it's going to come down to the wire, every bit of information that we've had for months now indicates that this is going to be a close election," he said.
Mr Minns said Labor's plan was to rebuild essential services beginning with hospitals and put an end to privatisation of state assets.
Both leaders have campaigned hard in key seats in Sydney's west, where one in 10 Australians live and many electorates are on a knife edge.
If Labor wins from opposition, it will be the first time the party has managed the feat since 1973.
On the eve of the election, Newspoll showed Labor leading the coalition 54.5 to 45.5 on a two-party preferred basis.
This would represent a 6.5 per cent swing against the coalition since 2019, putting Labor on a path to claim the 10 seats needed to form a majority government.
The poll put Labor's primary vote at 38 per cent compared to the coalition vote at 35 per cent and found Mr Minns had overtaken Mr Perrottet as preferred premier.
A raft of minor party and independent candidates vying for the cross bench could make the difference in the event of a minority government, with the Greens and teals vowing to hold the government to account on climate and other progressive reforms.
Rising financial pressure on families and businesses has put cost of living front and centre of the election, with both parties promising relief in the form of rebates on energy bills and caps on road tolls.
NSW Electoral Commissioner John Schmidt said special assistance was available for those who needed it such as the blind, deaf or anyone needing a translator.
Voters have until 6pm to cast their ballots.
