Ships of the Royal Australian Navy also assisted the Royal Navy in the blockade of the German High Seas Fleet. In February 1915, HMAS "Australia" joined the British Grand Fleet, and was made flagship of the 2nd Battle Cruiser Squadron. "Australia" was not involved in the Battle of Jutland; in April, the battlecruiser was damaged in a collision with sister ship , and she did not return to service until June. Three RAN ships were present during the surrender of the German High Seas Fleet; "Australia", "Sydney", and "Melbourne", with "Australia" leading the port division of the Grand Fleet as it sailed out to meet the Germans.
