Glenbrook and Lapstone will move from the Penrith electorate to the Blue Mountains seat in the 2023 state election following a decision by the NSW Electoral Commission on August 26.
Blue Mountains MP Trish Doyle has welcomed the decision, which was flagged last November under draft boundary changes.
"Since I was elected in 2015, I've lost count of how many times my office has been contacted by residents in these two villages and each time we've had to redirect them to Penrith. It just makes sense to align our state electorate with our local government area," said the Labor MP.
"Many constituents from Glenbrook and Lapstone have expressed over the years that they feel much more a part of the Blue Mountains than they do Western Sydney. They're baffled as to why they've been separated from the rest of the Blue Mountains when it comes to their community's representation in the NSW Parliament."
Lapstone and Glenbrook residents are currently represented by Liberal minister and Penrith MP, Stuart Ayres.
Mr Ayres has not reacted to last week's decision but in November he told the Gazette he would find it "personally disappointing" if Lapstone and Glenbrook were removed from the electorate.
"Redistributions are an independent part of the democratic process that protects the one person, one vote principle. I'll be dedicating all of my efforts to serving the people of Penrith no matter what suburbs the commissioners allocate to the electorate," he said.
Mr Ayres won the Lapstone and Glenbrook booths in the 2019 state election. He received almost 200 more first preference votes than Labor candidate Karen McKeown in Glenbrook, with a smaller margin of 86 votes in Lapstone.
Enrolment figures from 2020 show 54,385 Blue Mountains residents are located in the Blue Mountains electorate with 4,599 in the Penrith electorate.
