"Sydney needs a second airport but it is critical it has a rail link not just road links. The airport should have a curfew. What's good for the goose is good for the gander. If the eastern suburbs and the north shore have a curfew then so should the west."

Chifley: Ed Husic (Safe ALP, 10.5%) Opposed.

A 24-hour airport is "completely unacceptable for western Sydney residents who'll be forced to contend with something the other side of town doesn't".

Fowler: Chris Hayes (Safe ALP, 16.8%) Opposed

"How can this be supported by the community if questions [on jobs, infrastructure and curfews] remain unanswered?"

Greenway: Michelle Rowland (Marginal ALP, 3%) Opposed unless conditions met.

"Significant road and public transport infrastructure needs to be built, which is tied in with local employment – and it cannot operate for 24 hours."

Hughes: Craig Kelly (Safe Liberal, 10.7%) Support.

"I welcome the economic opportunities and infrastructure investment an airport for western Sydney will provide our region, and I would especially welcome the proposed Moorebank Intermodal's relocation as part of an integrated freight and transport precinct at Badgerys Creek."

Lindsay: Fiona Scott (Marginal Liberal, 3%) - Support conditional on roads and curfew.

"It's about building the right roads and infrastructure and the roads absolutely have to come first."

Macarthur: Russell Matheson (Safe Liberal, 11.4%) No reply.

Macquarie: Louise Markus (Liberal, 4.5%) No reply.

McMahon: Chris Bowen (ALP, 5.3%) Conditional.

"If there's going to be a second Sydney airport at Badgerys Creek, despite what the Deputy PM says, there must be a curfew and proper infrastructure for western Sydney."

Mitchell: Alex Hawke (Safe Liberal, 22.1%) Conditional.

"If Kingsford Smith retains a curfew then this airport, Badgerys Creek, should also have a similar curfew."

Reid: Craig Laundy (Marginal Liberal, 0.9%) Support.

"People often criticise governments for not making decisions beyond the electoral cycle. I applaud the Prime Minister for this decision, which will be a shot in the arm for the 1.3 million people expected to move into western Sydney over the next 20 years."

Werriwa: Laurie Ferguson (Marginal ALP, 2.2%) Opposed.

"I have grave doubts about the applicability of studies that are decades old and lofty visions of infrastructure and jobs being promoted by the big end of town."
