State Square Underground Car Park

The Territory Government is committed to revitalising Darwin’s CBD into a tropical, world-renowned destination, whilst supporting local business, creating more jobs for Territorians and boosting tourism.

The redevelopment of the State Square precinct and construction of a new underground car park is the first step in this major revitalisation program aimed at making the city a cooler and more public friendly place.

The new underground car park will be located below the existing grassed area between the Esplanade and Mitchell Street adjacent to Parliament House, commonly referred to as the Assembly Park.

The new underground car park will be funded from the $100 million commitment announced as part of Budget 2017 for Revitalising the Darwin CBD.


The new car park will see the relocation of existing surface car parks in State Square to an underground facility and will enable the redevelopment of the precinct by freeing up space and reducing heat generation.

The project will support local business, create jobs for Territorians and boost tourism in the Top End.

Project scope

The underground car park will accommodate 450 car parks and have a dual role as a Cyclone Shelter.

Tender awarded: May 2018
