They were converted again to LSIs in 1943 and took part in United States and Australian amphibious assaults in the South West Pacific Area.
[4][5] The Australian Defence Force's (ADF's) amphibious warfare capabilities were significantly expanded in 1982 when the landing ship heavy HMAS Tobruk was commissioned.
These ships were greatly modified and finally entered service in the late 1990s as the Kanimbla-class landing platform amphibious (LPA).
[8] On 1 February 2011 the Minister for Defence announced that repairing Manoora would not be cost effective given that the ship was scheduled to retired at the end of 2012 and that she would instead be decommissioned.
[9] In May 2011 the Australian Government chartered the civilian icebreaker Aurora Australis for two months to provide an amphibious capability while Tobruk was undergoing maintenance.
[10] In 2012, the Australian Government purchased the ADV Ocean Shield to provide the RAN with a third ship for humanitarian and disaster relief tasks.
[11] On 6 April 2011 Smith announced that Australia would buy Largs Bay and that the ship was expected to enter service with the RAN in 2012.
