Australian government to build second Sydney airport

The Australian government has announced it will build a second international airport in Sydney.
The A$5bn (£2.9bn, $3.8bn) airport will be located at Badgerys Creek, 50km (31 miles) west of the city's centre.
​
PM Malcolm Turnbull said the government would take on the project after the operator of Sydney's existing airport turned it down, citing financial risks.
It comes more than 70 years after the idea was first conceived, and follows promises from successive governments.

​The current Sydney Airport, 8km south of the city, has become increasingly stretched amid increased demand in recent years.
