Forrestfield, held by the Libs by a 2.2 per cent margin, was tipped to fall to Labor but Price said he took nothing for granted.
“While the polls were predicting a win, I didn’t rely on any polling being reported,” he said.
“Polling has been way off mark in recent elections and Forrestfield has always been a challenging seat when comes to elections.”

The Australian Workers Union official said he was humbled by the strong result in Forrestfield.
“It feels surreal and I am excited to have been given the opportunity to represent the electorate,” he said.
“I think the fact we took the time to listen to people and talk to them, while always putting forward a positive message about how we would address the issues raised by the community played a big part in the win.
“People were also strongly opposed to the sale of Western Power.”
Mr Price said he was ready to hit the ground running when he took office.
“The biggest issues raised were law and order, particularly concerns over hoons and security in their own houses,” he said.
“I will also be working hard to make infrastructure improvements in the area and address environmental issues such as the contamination at Adelaide Street.”
