The next international airport of Sydney could be located at the Nepean district, west of the city, which according to a plan drafted by a federal government taskforce, is best-suited to serve the growing needs of the premier global travelling hub.

Tasked to map possible expansions for the overstretched Sydney Airport, Gillard/O'Farrell Study on Aviation Capacity for the Sydney Region identified the district as the most ideal location for construction of new terminals and facilities that will relieve considerable loads from the existing structures.

At present, Sydney processes flights from in and out of Australia, including regional flights that the study said could be diverted to Bankstown, an Air Force facility also pinpointed as possible expansion site for Sydney Airport.

Sources cited by The Daily Telegraph revealed that economic modelling conducted by the joint study had concluded that Nepean bested other locations within Sydney, including sites that are easily accessible from the city's central business district.

However, the taskforce's findings are also laced with political and environmental considerations that could come with the establishment of a new aviation hub for Sydney.

For one, both the federal and state governments have previously expressed their resolves to oppose further airport construction within the city limits, with their stance set to be bolstered by the study's findings that Sydney's noise pollution would indeed increase with two international airports.

The Telegraph noted that Sydney residents could be subjected to an eight percent jump of disturbing aircraft noise once the two airports operate simultaneously.

That should be sufficient enough in deterring politicians from ever approving another airport within Sydney but the study also warned that if left on its present state, the city airport could encounter more pressing problems, both near-term and long term.

Fixing those issues, the joint taskforce said, could prove costly, running to billions of dollars.

Those considerations alone, The Telegraph sources said, could prompt both the national and state government to reconsider their position despite earlier assertions of shooting down any plan for a second airport in Sydney.

Yet as the study noted, the situation on the present terminals were nothing short of alarming, with the taskforce recommending that to temporarily relieve pressure, aircraft activities in the city should be raised to 85 per hour from its present level of 80.

That suggestion could raise howl among Sydney residents but aviation experts insisted that the authorities are hard-pressed to adopt short-term solutions to correct the existing glitches and possibly mull on long-term solutions too.
