Hills residents are stepping up the fight against plans for a new runway at Perth Airport, fearing it will shatter the tranquility of their quiet suburbs.

Plans are well underway for the massive runway expansion which the airport says is essential for the growth of the state.

But Darlington residents are worried the new flight corridor will direct planes over their quiet homes.

"We decided to come to Darlington back when it was peaceful and now we're faced with this," one resident told Today Tonight.

Another said: "It will probably impact our sleep, it will probably impact the price of our houses".

Every year 130,000 planes take off or land at Perth Airport and that number is expected to grow significantly.

Airport CEO Kevin Brown said the authority wanted to avoid getting caught out like it did during the mining boom when the number of plane movements hit 150,000 and existing facilities were unable to cope.

“With the Growth in our passenger numbers we're at that place and even looking back to 2012 during the resources construction boom, there were actually, it was gridlock ... we certainly don't want that to happen again,” he said.

The solution currently under consideration is the construction of a new parallel runway.

It would be built on the eastern side of the control tower and take five years to build. It's yet to receive government approval but the airport is currently undertaking consultation about what the impacts might be.

Air corridors determined by Air Services Australia and not airport operators.

While its unlikely public submissions will be enough to derail the parallel runway plan, they could have a baring on where planes fly.

Mr Brown said increasing capacity at the airport was critical for the state's growth.

"If people want to continue to be able to do their business efficiently, be able to go on holiday on time and not be delayed and for people that need to go to work to fly in and fly out it's important we actually provide the infrastructure to make that happen," he said.

Federal member for Swan Steve Irons said the runway construction would definitely go ahead.

"The approvals should be done by the minister next year and at the moment they're doing the draft air management space which the public are invited to make submissions to or anyone who might be affected by aircraft noise,” he said

Mr Irons said he wanted to make sure residents affected by aircraft noise were offered the same financial support to sound proof homes as residents in other cities have been.

"Both the constituents of Sydney Airport and Adelaide Airport enjoy and there's no reason why the Perth people shouldn't be entitled to amelioration scheme as well," he said.

But Hills residents say its not just noise in their houses that concerns them, it's their outdoor lifestyle and that can't be sound proofed.

“It’s all very well for them to say we'll do double glazing and what have you, (but) I live outside we promote our lifestyle in Perth as being outdoor people,” a resident said.

“This would put a flight corridor directly over those suburbs and from the information we can gather, it could be up to 19 planes a day.

“It would be a huge impact on the community and a huge impact on our lifestyle.”
