The Garden Island Defence Precinct (GIDP) is the only Major Fleet Unit on the East Coast of Australia. Its primary role is to support home-ported and visiting Navy Ships. The aim of the Stage One Project is to address significant deterioration of the Cruiser Wharf and Oil Wharf by providing a new, fully functioning and operationally flexible wharf at the northern end of Garden Island. The new wharf will be capable of berthing and facilitating maintenance work on Navy vessels. This consists of a 70m extension of East Dock Wharf and a 370m long new Cruiser Wharf.
