Millions of dollars will be spent in projects to upgrade infrastructure at Port Botany.

The NSW government will invest $314.4 million in projects to improve and upgrade infrastructure at Port Botany.

Ports and waterways minister Paul McLeay says a further $168.7 million will be spent on the $1 billion Port Botany Container Terminal Expansion project.

"This project underpins more than 500 jobs and will create a new 1.8 kilometre wharf, with five new shipping berths," says McLeay.

With a target of moving 40% of freight by rail, the government is investing $97.4 million in the development of the Enfield Intermodal Logistics Centre.

"This intermodal facility will allow for more efficient transfer of containers by train to and from Port Botany and help us deliver on this target," says McLeay.

Other projects supported in the 2010/11 NSW Budget include:
* $11.9 million invested in reducing congestion on local roads through the Port Botany Landside Improvement Strategy,
* $2.2 million for the second bulk liquids facility at Port Botany,
* $7.4 million for the vessel traffic services system, and
* $4.4 million for replacement pilot vessels.

Around $10.4 million will also be spent in the development of a new passenger cruise terminal.
