Australian Pacific force structure in 1914

How would a pre-World War I Royal Australian Navy with a battlecruiser, cruisers, destroyers, and submarines be structured, and who would worry about extra protected cruisers in the Pacific?

The Australian ships would join nearby Royal Navy forces. Cruisers would range across the Pacific, smaller craft would defend critical ports, and the battlecruiser would go wherever the wider fleet needed it.

Dominion ships would operate as part of an imperial fleet system rather than as isolated national assets. Light and protected cruisers would range across the Pacific, destroyers and submarines would guard critical ports, and the battlecruiser would go wherever the Royal Navy required a fast heavy unit. The German East Asia Squadron and Emden are the main early-war worries, with the Pacific largely quiet after 1914.
