NSW political leaders will go toe-to-toe in a bid to win over undecided voters in the final debate of the election campaign.
Premier Dominic Perrottet and Labor leader Chris Minns will look to expose any weakness in each other's policies or characters as the pair face off.
The debate, labelled the "last and most important" debate of the NSW state election campaign will see 100 undecided voters put questions directly to the two leaders on their vision for the state.
It will broadcast live on Sky News live from Penrith in western Sydney, where both parties are locked in a battle for key seats likely to decide the election.
Economic management is likely to dominate as Mr Perrottet and Mr Minns seek to drive home the message their fiscal plans are sound.
It comes after both sought to take the upper edge after analysis of their costings by the Parliamentary Budget Office earlier in the week.
Governance Institute of Australia chief executive Megan Motto urged voters to consider the ethical actions and the integrity of candidates as they prepared to vote.
"Good governance and an understanding of ethics and integrity from our leaders should set the bar for organisations across the nation, leading from the top to influence the public and private sectors and the institutions we rely on," Ms Motto said.
"Instead, it can appear that politicians are the ones dragging their heels to keep up with community expectations."
NSW Labor committed $14 million over the next four years to hire 100 additional National Park staff, to help them deal with weeds and pests in the area.
"After more than a decade of neglect, pests and weeds have exploded in our national parks, we need more boots on the ground to address this," Labor's Environment spokeswoman Penny Sharpe told AAP on Wednesday.
"These will be good, secure, local jobs where workers can build a career in these protected landscapes to tackle threats like weeds and pests."
The funding will come from unallocated funds in the state's Regional Growth Fund, and would not impact the budget over the forward estimates, according to the Parliamentary Budget Office.
