PM in final squeeze on NSW as Labor ascendancy looms

Prime Minister Anthony Albanese will make a string of NSW election day appearances as he tries to help secure Labor's supremacy across the Australian mainland.

Mr Albanese on Saturday shook hands with voters at a polling booth in West Ryde alongside the local federal member Jerome Laxale, who won the seat of Bennelong for Labor at the 2022 national poll.

He is later expected to appear in the inner west Sydney suburb of Balmain, which sits in his electorate of Grayndler but is held at a state level by the Greens.

Polls and bookmakers have the state opposition positioned to win the NSW election, a victory that would install a Labor government at federal, state and territory level everywhere except in Tasmania.

When asked about the prospect of Labor being in ascendancy across the mainland, Mr Albanese said he would work with whatever government was elected.

"But I'm very confident that I would work very closely with (NSW Labor leader) Chris Minns," he told reporters.

"I think he will make a great premier of NSW and I hope that he is successful today."

Mr Albanese added the string of senior Liberal ministers "bailing out" before the state election showed the Perrottet government "doesn't even have confidence in itself".

"It's time for a change of government and I hope that happens today," he said.

Several other senior Labor figures were also on the hustings, including Environment Minister Tanya Plibersek and Indigenous Australians Minister Linda Burney.

In contrast, federal Opposition Leader Peter Dutton has been notably missing from the coalition's campaign throughout the lead-up to the NSW poll.

Premier Dominic Perrottet batted away questions about Mr Dutton's absence on Saturday, telling Seven's Sunrise program that he didn't need a "wingman" for his election pitch.

"This is an election on NSW issues, it's a NSW election," he said.

With the election result expected to be close, Greens leader Adam Bandt said a shared-power government was likely and a vote for his party would help ensure the coalition didn't strike a deal with One Nation to secure victory.

"Today's a big day for NSW. By voting for the Greens, you can kick out the Liberals and push the next government further and faster on climate action," he said on Twitter.
