NSW Labor has vowed to start building a key transport link to high-density Sydney boroughs in its first term of government, signalling its intent to wrestle back a key Liberal seat.
The $200 million promise to start major construction works on the Parramatta Light Rail extension to Sydney Olympic Park by 2027 comes after the project's completion time blew out to 2031.
Labor is suspicious the government's only monetary pledge currently - $603 million to planning works and to build bridges over waterways - means the project is in danger of being scrapped in favour of busways.
