HEATHCOTE MP Lee Evans retained his seat comfortably despite an 11.5 per cent swing to Labor.
As of Monday morning, with counting continuing, Mr Evans had achieved 57.8 per cent on a two party preferred basis, and Labor 42.52.
This compares with a two party preferred result in 2011 of 62.9 per cent for Liberal and 37.1 per cent for Labor.
"It was a good result considering the amount of money put into the campaign by the union movement," he said.
"In comparison with other seats they were concentrating on Heathcote.
"Obviously, the high tide mark was 2011 but I am buoyed by the results, particularly in Engadine, Helensburgh, Sutherland and Menai.
"I think the results show negative campaigns don't work."
Labor candidate Maryanne Stuart congratulated Mr Evans on his re-election.
"It was a very strong local result for us, one of the highest swings to Labor in the state," Mrs Stuart said.
"I spoke to lots of people who said they had never voted Labor before but did at this election.
"They were concerned about funding cuts, affordability issues and the train timetables."
Mrs Stuart said she would continue to advocate for better local services.
"I have lived here for 44 years. It's my home and I care very much about it."
