No second airport for Sydney
The Government sold a 100 per cent stake in Sydney Airport Corporation Limited (SACL) in June 2002 for AUD$4.233 billion to the Southern Cross Airports Corporation. This sale agreement of SACL approved a first refusal over the development and operation of the second Sydney airport for a period of 30 years.
I don't think that SACL will be quietly allowing a second airport to be built in the near future.
