Premier gets sporty, Minns looks to drive Monaro to win

The NSW premier has committed to upgrade an ageing sports club in a Liberal stronghold, while Labor leader Chris Minns is trying his luck in the bellwether seat of Monaro as he presses his claim to give the state a fresh start.

With two days of campaigning left until election day, the leaders are back on the hustings in a last-ditch bid to court wavering voters, although about 12 per cent have already cast their ballot, while more than 500,000 have applied for a postal vote.

Buoyed by a strong performance against Premier Dominic Perrottet in a final campaign debate on Wednesday night, Mr Minns waded into the government territory of Monaro on Thursday.

Nationals MP Nichole Overall, who took Monaro in a by-election after former deputy premier John Barilaro retired last year, holds the seat with a margin of 11.6 per cent.

Centred around Queanbeyan and held by a member of government for 86 of the past 96 years, the electorate is a critical part of Labor's potential path to minority rule.

Mr Minns appeared at a Queanbeyan cafe at dawn with Labor's candidate, Steve Whan, to announce $650 million funding for urgent road upgrades in regional NSW.

"We know many parts of this part of NSW have been affected by flooding, like many regional towns," he told reporters.

"There's been major problems with road infrastructure, potholes in particular.

"Unsafe grading right across NSW is one of the leading reasons why Labor has announced a $650 million emergency road package for regional NSW.

"We've spoken to mayors ... who've told us in many cases they're not potholes, they're craters that cars have been falling into."

There was speculation he would be joined by Prime Minister Anthony Albanese on the hustings, but Mr Minns said the PM had a busy day with federal parliament sitting.

"He's been a big supporter of our efforts to overturn 12 years of coalition government in NSW," he said.

Meanwhile, the premier's campaign bus headed to the seat of Drummoyne to announce $500,000 to upgrade facilities at St Luke's Oval.

The seat had been comfortably held by Liberal John Sidoti since 2011, but he is retiring after the Independent Commission Against Corruption found he engaged in serious corrupt conduct last year.

Mr Sidoti has consistently denied any wrongdoing.

"We're out every day fighting for every vote," Mr Perrottet said, alongside candidate Stephanie Di Pasqua.

"I know that Drummoyne is a much better place today because of the Liberal government."

Earlier, Mr Perrottet said he remained optimistic despite polls predicting more than a decade of coalition government will end on Saturday.

When asked which seats he hoped to win, he nominated Leppington in Sydney's southwest and Mr Minns' ultra-marginal electorate of Kogarah.

"There's a lot of seats and we're not taking any vote for granted," the premier told Sydney radio 2GB.

The leaders made their final pitches to 100 undecided voters in Penrith on Wednesday night, with western Sydney crucial to electoral success and where one-third of voters live.

After the final debate of the campaign, 48 per cent of the audience said Mr Minns came out on top, 32 per cent went Mr Perrottet's way, with the remaining 20 per cent undecided.
