The Canberra class is a ship class of two landing helicopter dock (LHD) ships built for the Royal Australian Navy (RAN). Planning to upgrade the navy's amphibious fleet began in 2000, based on Australian experiences leading the International Force for East Timor peacekeeping operation. With a new climate for growing Australian Navy spending, a desire existed for forward defence capability for landing and supporting troops on Asian territory, that had never existed in Australian history, even with the old Majestic-class light fleet carriers, HMAS Melbourne and HMAS Sydney in the 1970s. In 2004, French company Direction des Constructions Navales (DCN) and Spanish company Navantia were invited to tender proposals, with DCN offering the Mistral-class amphibious assault ship and Navantia proposing the "Buque de Proyección Estratégica" design (later commissioned as Juan Carlos I). The Spanish design was selected in 2007, with Navantia responsible for construction of the ships from the keel to the flight deck, and BAE Systems Australia handling the fabrication of the combat and communications systems.^[1] Finally, Siemens (Germany) supplied and fitted the azimuth thrusters.^[1]

Construction of the first ship, HMAS Canberra, commenced in late 2008, with the hull launched in early 2011, and sea trials in early 2014. Canberra was commissioned in November 2014. Work on the second vessel, HMAS Adelaide, started in early 2010. Adelaide was commissioned in December 2015. They are the largest vessels ever operated by the RAN, with a displacement of 27,500 tonnes (27,100 long tons; 30,300 short tons).

The ships are home-ported at Fleet Base East in Sydney (which has prompted complaints from nearby residents about machinery noise, exhaust fumes, and blocked views) and will regularly operate out of Townsville, the location of Lavarack Barracks, home of the Australian Army's 3rd Brigade. In addition to being located in North Queensland close to Asia and the Pacific Islands, one of the 3rd Brigade's infantry battalions, the 2nd Battalion, Royal Australian Regiment (2 RAR), was selected to become the Army's specialist amphibious infantry battalion.
