Australia's HostPlus CEO David Elia, speaking at the CAPA Australia Pacific Aviation Summit, estimated (09-Aug-2013) a second Sydney airport at Badgerys Creek would cost AUD2.5 to AUD3 billion (USD2.3 to 2.7 billion), not including surrounding infrastructure. An airport at Wilton is estimated to cost AUD3.5 billion (USD3.2 billion) due to land acquisition. Mr Elia estimated an airport at Badgerys Creek would require seven to 10 years of planning and another seven to 10 years to construct. Mr Elia said potential investors in a new airport project would require "some element of government underwriting" to establish a minimum income stream.
Second Sydney airport estimated to require investment of up to USD3.2bn

Air Canada and Virgin Australia codeshare, in a North American market dominated by Qantas
From early 2017 Air Canada and Virgin Australia introduce a tidy new partnership. Virgin Australia receives improved access to Canada – a market its JV partner Delta cannot sufficiently cover from their shared Los Angeles gateway. Air New Zealand's sixth freedom option, via Auckland, is the third largest transportation choice by Canadians visiting Australia. Since Virgin noisily fell out with Air NZ, the Australian airline is looking to reassert itself in Australia-North America markets that it had quietly let Air NZ dominate. Virgin has already announced plans to resume trans-Pacific services from Melbourne, which Air NZ took traffic from.
Air Canada is growing in Australia, expanding from its 2007 Sydney service with a 2016 Brisbane service, and perhaps soon Melbourne as well. Air Canada needs a partner for domestic and New Zealand connections as it expands its footprint and grows ahead of market demand. There is some conflict, since Air Canada - as it does for its expanding Asia and Europe presence – will look for USA sixth freedom traffic. Air Canada has favourable connections via Vancouver to a handful of American cities, including New York.
United Airlines reduces seasonal capacity in the competitive US-New Zealand/Australia market
After rapid growth in the market between North America and Australia/New Zealand, an airline has finally blinked: United Airlines will change its sole New Zealand service, San Francisco-Auckland, to only operate seasonally. United will rely on its JV partner Air New Zealand.
Auckland is less important for United than for American Airlines and its codeshare (but not JV) partner Qantas. Qantas has exited the Auckland-Los Angeles market, so American's entry to New Zealand gives it two nonstops from both Australia and New Zealand, enhancing presence across the region and making it easier to bring American visitors to both Australia and New Zealand.
United's adjustment to a seasonal service will mean that the New Zealand-North America (excluding Hawaii) market will expand by a reduced 10% instead of 17%. Even with this downward change there will be 17% more capacity than in the previous record year of 2008.
