Port Botany, Deep-water seaport in Sydney, Australia

Port Botany is a deepwater seaport on the northern shore of Botany Bay in Sydney, next to Sydney Airport. It holds three container terminals, the northernmost opened in 1979 as Brotherson Dock, plus a bulk liquid terminal completed the same year. The third terminal, finished in June 2011, added 63 hectares of reclaimed land and 1.85 km of wharves berthing five vessels.

The port began operations in 1979 and grew into a major center for regional trade traffic. Since then it has become an essential part of Australia's infrastructure for exports and imports.

The port area includes Molineaux Point, which commemorates the connection between Sydney Ports Corporation and Yokkaichi Port Authority from Mie, Japan.

The port lies in northern Botany Bay beside Sydney Airport, with road and rail links for cargo. Public access to working areas is limited, so visitors should keep to designated viewpoints outside the terminals.

The third container terminal, finished in June 2011, reclaimed 63 hectares of land and added 1.85 km of wharves berthing five vessels; its builders, Baulderstone and Jan De Nul, won the Australian Construction Achievement Award. The A$515 million project was twice the size an independent 2004 Commission of Inquiry recommended.
