Australia’s Battle Cruiser

In the summer of 1909, the Royal Navy faced increasing pressure to increase its fleet of modern dreadnought battleships and battle cruisers while maintaining its commitments around the globe. To help meet this and spread the costs, the British government proposed that Australia, New Zealand, South Africa and Canada each fund and man a squadron of one new armored cruiser, three light cruisers and six destroyers.

Of the four, only Australia took up the full proposal. One armored cruiser and three smaller cruisers would be ordered immediately, for construction in British shipyards. The Australian government would pay for their construction and upkeep, and they would be manned by Australian personnel. During wartime, they would be at the disposal of the British Admiralty. New Zealand could not meet the same level of commitment, but did agree to fund a new armored cruiser and present it to the Royal Navy. South Africa and Canada rejected the proposal outright.

At the time of the conference, Britain's most recent armored cruiser, Defence, had been commissioned in February — after a considerable delay as resources went instead to the new battle cruisers of the Invincible class. The third battle cruiser completed in March 1909, and one more, Indefatigable, had been laid down in February to a slightly improved design.

Events were moving quickly when the two Dominions made their offers. The Admiralty intended to order two capital ships under the 1908 program, the battleship Neptune and the battle cruiser Indefatigable. The 1909 program initially was to also include two battleships, near-sisters of Neptune, and the two battle cruisers provided by New Zealand and Australia. Rumors of increases in the German building program sparked public pressure for eight new ships rather than four (or two, depending on who was doing the counting). Six additional ships were added to the 1909 program: four "super dreadnoughts" of the Orion class, and two battle cruiser equivalents, Lion and Princess Royal.


Although Lion was laid down nine months before Australia and New Zealand, the two Dominion ships repeated the inferior Indefatigable design as originally ordered. Lion was a far more capable ship, almost half again as large with much greater firepower. Not willing to lose the commitments, the Admiralty did not press the Dominions to switch to the more expensive Lion (£2.1 million as opposed to £1.7 million for the smaller battle cruiser), even though the Dominions had budgeted two million each for the cruisers. This failure left Royal Navy with far less capable ships when war erupted five years later.

Australia completed in June 1913, and sailed for her homeland the next month, stopping at Capetown for a visit carefully calculated to show the Union's leadership what they were missing. She served as flagship of the new Royal Australian Navy for less than a year before war broke out and she took on a major role in its early weeks. Maximilian Reichsgraf von Spee's German East Asia Squadron was on the loose in the Pacific, and Australia was faster than any of his ships and capable of blowing all of them out of the water.

At 18,500 tons, Australia was bigger than either of Spee's 12,800-ton armored cruisers. She could make almost 27 knots, a considerable edge in speed, and her eight 12-inch guns gave her greater firepower than any ship in the Pacific except the newest Japanese battleships. Rather than deploy the big cruiser to hunt down and eliminate the threat posed by Spee to Allied commerce and military convoys, the Admiralty kept Australia tied to the invasions of German New Guinea and Samoa. Not until Spee wiped out Sir Christopher Cradock's cruiser squadron was Australia ordered to pursue, heading for South America on 1 November. She was still on her way when two British battle cruisers annihilated Spee's ships, and suffered grounding damage in the Straits of Magellan on New Year's Day. She also sank a German supply ship along the way.

Australia fires a broadside, but only as a training exercise.


Australia arrived in England on 28 January 1915, four days after the Battle of Dogger Bank, and in early February she re-deployed to Rosyth, Scotland as flagship of the Second Battle Cruiser Squadron. She participated in numerous Grand Fleet operations, and on 22 April 1916 rammed her sister New Zealand during heavy fog. She spent the next six weeks under repair, missing the Battle of Jutland. Australia served as squadron flagship for the rest of the war and led one of the two long columns of Allied warships that accepted the surrender of the German High Seas Fleet in November 1918, but Australia had never fired her guns in anger.

She returned home the following spring, arriving in Freemantle in May 1919. A few days later, part of the crew mutinied when ordered to sail for Sydney — they had not had their fill of the joys of Perth. Five crewmen were sentenced to prison terms, but all were released by the end of the year. The big cruiser conducted training cruises but soon grew too expensive for the peacetime budget and she went into reserve at the end of 1921. The following year, she was sacrificed at the Washington naval limitations talks, designated for destruction to end the economically-crippling world naval arms race.

Towed off Inner South Head near Sydney, the battle cruiser was scuttled in April 1924. "In her passing she symbolizes our contribution to the cause of peace," Prime Minister Stanley Bruce noted. "We shall never forget that in the eventful days of 1914, when the fate of civilization hung in the balance, it was the presence in the Pacific of the Australia, manned by Australian seamen, that saved our shores and our shipping from the fate which overtook less fortunate nations."

This is the end. Australia sinks off Inner South Head, 12 April 1924.


Australia's sacrifice had not been popular within the Royal Australian Navy, with some officers arguing that she should not be counted against the British force total. The RAN compensated for her loss with two new County-class heavy cruisers, but many never fully accepted the destruction of the ship when she remained in excellent condition, having taken no battle damage.

Despite her good material condition, had Australia somehow survived the Washington Treaty thanks to her Dominion ownership, she would have required a serious overhaul to even approach modern standards. The Cockatoo Island shipyard in Sydney harbor had built destroyers and a light cruiser during the First World War and a seaplane carrier in the late 1920s. Rebuilding the battle cruiser would have provided jobs for a starved industrial economy during the 1930's; the Australian government had attempted to arrange construction of a King George V-class battleship there for the same reasons.

The battle cruiser Renown underwent a total rebuilding in the late 1930s, and Australia's reconstruction along similar lines would have required extensive changes. Only her importance as a political symbol — and the jobs generated at Cockatoo — could have justified the expenditure on such an old warship of limited fighting ability. Much like the rebuilding of Hood posited by Kristin Ann High in another Daily Content piece, Australia's reconstruction would have resulted in a much more capable ship.

Her continued existence could only be justified as a "Treaty Cruiser Killer," the type of warship proposed by numerous naval writers during the decades between the world wars. Australia's 12-inch main battery was much too light for combat against enemy battleships, but against cruisers limited to 8-inch guns she would hold a significant tactical advantage. To exploit that edge would require much more speed. As built she produced about 47,000 horsepower and reached 26.9 knots on trials. To make the 33 knots needed to run down heavy cruisers, she would require at least three times that output, a new bow form, and she would probably need to be lengthened as well.

Installing new Parsons turbines and three-drum oil-fired boilers would result in a heavily re-designed amidships section, and the two wing turrets would have to be removed. The casemates for her 4-inch guns would be plated over, and her two torpedo tubes and their handling rooms removed. In their place, the newly opened spaces amidships would have been ideal for a large array of the 5.25-inch dual-purpose mounts fitted in King George V-class battleships and other large warships. There would also have been room for an athwartships catapult and a seaplane hangar.

What emerged would not have been a true battle cruiser so much as an oversized heavy cruiser. As such she would have been extremely useful as a counterweight to the big Japanese heavy cruisers or as an escort for fast carrier forces, much as the Japanese saw their own rebuilt battle cruisers. Renown's reconstruction cost more than £3 million and Australia's would probably have been in the same range: the three Perth-class light cruisers purchased in 1935 would likely have been sacrificed to balance the expense.

Cardboard is much cheaper than steel, and so we have some alternate counters for your use available here. There is Australia as rebuilt for use in Second World War at Sea scenarios, and Australia as a member of the Lion class for Great War at Sea. In each case she flies the "Australian White Ensign," proposed as early as 1909 but not officially adopted until 1965.

For a ship that never saw combat, Australia appears in several of our Great War at Sea series games, making her presence felt in Jutland and most notably in the discontinued Cruiser Warfare. You can also try her out in her rebuilt version in Strike South or Eastern Fleet.
