They spent most of the war patrolling the North Sea, and participated in most of the battles there, although only "New Zealand" was in the United Kingdom when the war began. "Indefatigable" was in the Mediterranean where she pursued the German warships and as they fled towards Turkey and "Australia" was flagship of the Royal Australian Navy in Australian waters where she helped to secure the German Pacific colonies and searched, unsuccessfully, for the German East Asia Squadron before sailing for the United Kingdom in December 1914. "New Zealand" participated in a number of the early actions in the North Sea including the Battle of Heligoland Bight and the inconclusive Scarborough Raid. "Australia" was still under repair after a collision with "New Zealand" before the Battle of Jutland so only "Indefatigable" and "New Zealand" were present where the former was destroyed by a magazine explosion. Both "Australia" and "New Zealand" spent much uneventful time at sea after Jutland waiting for the next appearance of the High Seas Fleet, but that had been forbidden by the Kaiser. "New Zealand" conducted Admiral Jellicoe on his tour of India and the Dominions after the war while "Australia" returned home where she again became the flagship of the Royal Australian Navy. "New Zealand" was sold for scrap in 1922 while "Australia" only lasted two years more before being scuttled to comply with the terms of the Washington Naval Treaty.
