2nd Syd Airport ...No curfew, page-4

Hi Sloth27 - One documents which may help give a good understanding of future plans for Sydney Airport is their Master Plan 2033. Just go on their website and search on Master Plan and it will come up. Also if you check their ASX announcements there is a notification that SYD has been given a Notice to Consult on the Western Sydney Airport as their current lease provides that they have first right of refusal to build and operate the new airport.You might also like to check the website for http://www.westernsydneyairport.gov.au/
