# DMS Maritime

DMS Maritime, formerly Defence Maritime Services, is a company providing port services to the Australian Defence Force and Marine Unit. It is a subsidiary of Serco.

## History

Defence Maritime Services was founded in 1997 as a 50:50 joint venture between P&O Maritime Services and Serco to fulfill a contract to organise tug boats and ferries and supply and maintain small boats for the Royal Australian Navy (RAN). In 2012, Serco bought out P&O's shareholding.
Headquartered in Sydney, it has operations in Cairns, Darwin, Dampier, Fremantle, Western Port, Jervis Bay and Sydney. It currently operates eight oceangoing vessels and over 100 harbour craft and has around 350 staff. The services DMS is contracted to provide to the RAN include operating tug boats and lighters at RAN bases, training members of the RAN, and maintaining RAN warships.
