MULGOA MP Tanya Davies intends to recontest her seat at the 2015 state election, despite major changes under the boundary redistribution.
Losses include St Marys, Colyton, Oxley Park, Claremont Meadows , which will come under the Londonderry electorate, currently held by Liberal Bart Bassett, who is yet to indicate his intentions.
Other losses include Greendale, Badgerys Creek, Bringelly and Wallacia (in part).
Gains include Erskine Park,Mount Vernon Abbotsbury, Cecil Hills, Middleton Grange and Kemps Creek.
"While I will miss representing those individuals, families and business owners who have been allocated to other electorates, I am likewise excited about the constituents I will be advocating for and eagerly look forward to getting to know and work with in these new communities," Mrs Davies said.
"I intend to recontest the seat of Mulgoa to continue providing an effective and compassionate parliamentary service to my electorate."
Mount Druitt MP Richard Amery is keeping his cards close to his chest.
It's 30 years to the day since he was elected as Riverstone MP.
He stood for Mount Druitt in 1991 after an electoral re-distribution.
As the Father of the House, he is the longest-serving member of the NSW lower chamber.
An afternoon tea was held in Mr Amery's honour at his office yesterday.
"My future is still being weighed up and I'll make the decision closer to the time," he said.
Mr Amery gains Dean Park and Stonecutters Ridge in the redistribution.
Losses include Willmot and parts of Emerton, that become part of Londonderry.
"I'm familiar with Dean Park, as it was part of my electorate previously," Mr Amery said.
"I'm sad to lose Willmot. There are a lot of issues around there, which has one of the best community newsletters in the region."
An overhaul of Londonderry sees the Liberal margin decline from 12.3 per cent to an estimated 5.3 per cent, according to the ABC election analyst Antony Green.
"Londonderry is a big chance for Labor at the next election," Mr Amery.
"The Liberals hold all three levels of government but I'm starting to feel things will improve for Labor, given their performance at state level."
