Wendy Tuckerman, who won the seat ahead of Labor's Ursula Stephens at the March State poll, delivered the speech on Wednesday in front of family, friends and supporters.

She noted that Millicent Preston-Stanley was the first woman elected to the Parliament in 1925.

"In the words of Millicent, 'Women have a contribution to make to the life of the nation that only women can make,'" Mrs Tuckerman said.

"I am proud of being a female role model in my community. I hope to inspire, encourage and support young girls and women to chase their goals, to serve their community and, most importantly, to believe in themselves."

She paid tribute to female role models who had helped her during her election bid, including Premier Gladys Berejiklian and former Goulburn MP Pru Goward, who watched from the gallery. Former Southern Highlands MP Peta Seaton and NSW Upper House member Natasha McLaren-Jones were also there.

"I indeed have formidable role models to emulate, and I look forward to their counsel as I make and establish my own pathway in this House," Mrs Tuckerman said.

The MP told Parliament that she was very proud to be representing such a diverse electorate which was rich in agricultural produce and home to some of the sector's leading experts.

Mrs Tuckerman said her experience in local government had reinforced the importance and strength of community.

"As the member for Goulburn, I will harness the sense of community that exists within my electorate to ensure our strengths are identified and opportunities are created just as I have done during my years in local government," she said.

"As a young mother of two I became interested in local government and I was keen to represent my community as I thought I could make a difference."

She served on Boorowa Council for 12 years from 2004, nine of those as Mayor, before being appointed as the Hilltops Council administrator. Mrs Tuckerman is also a former AFP investigator.

The MP said it was vital to support communities with adequate services, particularly those to meet the needs of an ageing demographic and the "most vulnerable."

"I will fight for a world-class health system that provides for the sick and infirm, to be delivered by the best skilled practitioners, and support and access no matter where people live," she said.

Mrs Tuckerman also pledged to support drought affected communities and to "never forget the hand that feeds us." She also promised to advocate for small business and to ensure that they were afforded "world-class technology and connectivity, just like in the city."

The provision of safe, secure, efficient and sustainable water supplies and waste services was also high on her agenda.

"I am a strong believer that it is not what is said, but rather what is delivered that is important," Mrs Tuckerman said.

She thanked numerous supporters throughout her campaign and paid tribute to her family.

"In this, my first speech in this place, I wish to pledge to all my constituents that for as long as I have the honour and privilege to represent them in this place, I will always put the communities and people of this electorate first," Mrs Tuckerman said.

"I will dedicate the next four years and beyond to prove to my constituents that their trust in me is well placed, because for me, first and foremost, politics is about people and community."

The newly minted MP celebrated the occasion with husband Michael, sons Bradley and Thomas and their wives Brittney and Katie. New granddaughter Letty, born on May 2, was also on hand, along with parents Pamela and William Porter.
