Former Liberal member and Howard government minister Jackie Kelly has announced she will run as an independent in next year's New South Wales state election.

Ms Kelly will run for the seat of Penrith in Western Sydney.

She served as a federal Liberal member for more than a decade, but quit the party in October in protest against the party's lack of reform and public consultation.

Now she has set her sights on the Federal Government's plan to build a second Sydney airport at Badgerys Creek.

"We don't even want an airport in Western Sydney unless there is significant infrastructure and not just WestConnex," she said.

"Not just an upgrade of Bringelly and Northern roads, we want serious infrastructure right across Western Sydney from Prospect out to Castlereagh."

Ms Kelly said she was also frustrated by traffic congestion in Sydney's west.

"I'm standing as an independent for Penrith in the state election but my major platform is against Badgerys Creek airport," she said.

"My secondary platform is about Western Sydney getting the infrastructure it deserves and not just the peanuts for Penrith we've been getting with this government."

She said some of her former colleagues have been angered by her comments.

"I have a lot of friends in the party and I also have as of now quite a few enemies," she said.

"I think the Liberal Party used to be quite open to dissent, it used to be a position where we could have arguments.

"Now consultation is the RMS (Roads and Maritime Services) coming out setting up shop and saying here is the M9 route, here is the train route, that's our consultation.

"Residents of Western Sydney are really fed up with it."

Earlier this year Ms Kelly, who held the Western Sydney seat of Lindsay, launched a blistering attack on Tony Abbott.

She warned she would "do the prime minister over" with a "soccer mums" grassroots campaign against his plan to build a second Sydney airport in her old electorate.

Last month she labelled the NSW Liberal Party "a joke" and resigned her membership after 19 years.
