Newcastle lawyer Nell McGill will contest the seat of Shortland for the Liberal Party in the May federal election.
Ms McGill will challenge incumbent Labor MP Pat Conroy who holds the seat with a 9.94 per cent margin.
"I feel really positive about it [running for the Liberal Party]," Ms McGill said.
"We saw in the state election that there were small swings to the Liberals in Swansea and Charlestown. As much as it is a big margin I really believe it is possible."
Ms McGill joins cardiothoracic nurse Katrina Wark, who was announced as the Liberal Party's candidate for the seat of Newcastle on Wednesday.
The party's other candidates are expected to be announced next week.
Ms McGill said she believed voters separated state and federal issues.
"Even though we have just had a state election I think people are already thinking about the federal policies that are going to affect them," she said.
"I think that people can differentiate between the different elements of funding and policy between state and federal."
The mother of three said she would like to see the electorate's tourism potential given a higher priority by all levels of government.
"It's the most beautiful place to live and the people are great," Ms McGill, who lives at Whitebridge, said.
"It would be good to see some tourism investment because of the beautiful nature of the electorate."
More than 20 per cent of the electorate's population is aged 65 and over, about 5 per cent higher than the national average.
Ms McGill said one of her personal priorities would be to improve aged care services and protect ageing Australians.
"More than 7,300 Shortland residents would be hit by Labor's Retiree Tax which abolishes tax refunds for share dividends," she said.
"This changes the goal posts and punishes those who have worked hard and saved for retirement all of their lives."
