Melanie Gibbons was preselected uncontested for the seat of Kiama on Tuesday night, just hours before candidate nominations for the March 25 election close at midday on Wednesday.
Her political reprieve comes after she lost preselection in her seat of Holsworthy last year to former deputy mayor Tina Ayyad and then failed in a bid to run on the party's upper house ticket.
Ms Gibbons has been the Holsworthy MP for seven years, and before that the member for Menai for four years.
She is now up against Kiama's incumbent independent MP Gareth Ward, who was dumped from the Liberal Party and suspended from parliament last year after being charged with sexual and indecent assault.
He denies any wrongdoing and the case remains before the courts.
The Liberal Party has now selected candidates for all seats, after scrambling to finalise 15 candidates on Tuesday, before the midday deadline.
Meanwhile, Premier Dominic Perrottet and Labor Leader Chris Minns will face off in an hour-long debate on the Seven Network on Wednesday.
Earlier, Labor announced a specialist service to help women navigate underpayment and sexual harassment would be available in NSW for the first time in 18 years if the party can win government.
Not-for-profit working women's centres operate in three states and territories to help those not represented by a lawyer or union deal with workplace issues, including sexual harassment, parental leave and underpayment.
Sex Discrimination Commissioner Kate Jenkins singled the centres out in her Respect@Work report in 2020, recommending all jurisdictions without them consider establishing them and provide recurrent funding.
It will end an 18-year absence of the centres in NSW by working with the federal government, industry, and stakeholders, and providing $2 million to keep them operating at their full potential, Labor says.
Deputy Labor leader Prue Car said the promise was part of a $13.8 million package that includes $5.8 million to provide coaching and employer connections to get more women into work.
Building on a successful pilot by the federal Office for Women, the Future Women's Jobs Academy would support 1000 women across two years to "become job-ready" through an online resources hub, professional development, coaching and mentoring.
Women's workforce participation rate has grown to 61.4 per cent under the coalition government but remains well below the men's rate of 70.9 per cent.
Meanwhile, the premier announced $7 million for grants to research ovarian and other gynaecological cancers.
"We want to give women affected by these terrible diseases, which often have very poor prognoses, the best chance of survival," he said.
