* Australia to build publicly-funded 2nd airport for Sydney
* Private sector deemed $3.8 bln project too risky
* Qantas sees potential for low-cost hub
(Recasts throughout, adding CEO and economist quotes)

SYDNEY, May 2 The Australian government said on
Tuesday it will build a A$5 billion ($3.76 billion) second
international airport in Sydney, ending decades of indecision on
the project which private investors deemed too risky and
The government stepped in after Sydney Airport Holdings
declined its right to develop and run the new hub, even
though its withdrawal promises to end its airport monopoly in
Australia's biggest city and tourist drawcard.
But the site at Badgery's Creek is 40 km (25 miles) from
central Sydney compared with 8 km for the existing airport, and
critics question its viability without a rail link to the city.
Airlines also warn that fees will need to be low to encourage
them to switch.
"It's a burden that the government has the capacity to bear
- the burden being not simply the costs, but the risks,"
independent economist Saul Eslake told Reuters.
"Nobody really knows what the demand for services at this
facility is likely to be."
Prime Minister Malcolm Turnbull said the project would
inject more than A$1.9 billion into the economy during the
construction phase alone.
It is expected to open in late 2026 and boost inbound air
passenger numbers to Sydney by about a quarter, or 10 million
people per year in the early years.
RISK AND RETURN
Sydney Airport, which had first right of refusal to build
the airport, earlier on Tuesday said it would not proceed with
the project which it had previously called "deeply uneconomic".
"The risks associated with the development and operation of
the airport are considerable, and that will continue for many
decades without commensurate returns for our investors," Sydney
Airport Chief Executive Kerrie Mather said at the Macquarie
Australia Conference, an economic forum.
Sydney Airport will lose its monopoly as a result, but it
could benefit from lower-margin domestic traffic migrating to
the second airport, allowing it to accept more lucrative
international traffic, analysts say.
The semi-rural site at Badgery's Creek on Sydney's western
outskirts was first mooted in 1946 as the limits of the first
airport - hemmed in by suburbs and the sea in the city's east -
The new airport is initially envisaged as a low-cost hub for
mostly domestic flights by airlines like Qantas Airways Ltd's
budget arm Jetstar. Sydney Airport has the highest
landing fees in Australia.
"You need to have it like Stansted, a low-cost operation, an
airport that's designed for those purposes," Qantas Chief
Executive Alan Joyce said at the Macquarie event, referring to
London's low-cost hub.
While the opposition Labor Party supports a government
build, shadow transport spokesman Anthony Albanese on Tuesday
said it was "essential" for a rail line to be "up and running
from day one".
The government said it is studying railway routes but has
not promised a line as part of the initial build.
It also flagged its possible sale after construction.
"In due course you would expect this infrastructure asset to
return to private ownership," Infrastructure Minister Paul
Fletcher told Sky News television.
Turnbull said more details on the project would be provided
in next week's federal budget.
