It is the eighth time Ms Ley has won the Farrer election and she said she was humbled by the support of the voters.
Ms Ley said residents cast their vote based on what she had done during the past three years in the position.
“I’ve worked hard over three years and we saw that in the result on Saturday,” she said.
The Farrer seat was one of the few Liberal-held seats in NSW to see an overall first preference swing in favour of the Liberals.
“Most Liberals (seats) lost traction,” Ms Ley said.
“It (my increase in primary votes) has given me the energy and enthusiasm to keep going and representing my electorate,” Ms Ley said.
She paid tribute to all those who helped in her campaign.
“Thank you to everyone who came out to support me,” Mr Ley said.
“A campaign is not a solo effort, it is a team effort.”
Ms Ley touched on the fact Labor won the Federal election, with Anthony Albanese the new Prime Minister.
“We have a Labor Government. I’m devastated by that,” she said.
“It’s of concern to water-dependent communities.
“My job is to fight now for every drop of water Labor want to take away.”
