What fictional Australian super-cruisers would change

How would the World of Warships Auckland, Cerberus, and Encounter-class cruisers affect Australian naval strategy and treaty-era cruiser design?

They would influence treaty baselines and demand a much larger RAN; wartime employment would likely emphasize Mediterranean, fleet, and carrier-escort duties over commerce raiding.

This answer concerns fictional World of Warships vessels rather than ships that served in the Royal Australian Navy. If cruisers such as Auckland, Cerberus, and the Encounter class existed before the treaty system, their size and armament would help define the negotiating baseline; the County class would still follow treaty limits rather than simply grow from Hawkins. Operating the expanded fleet would require roughly three or four times the historical Australian naval personnel, a level that may be physically possible but financially doubtful. In wartime, the largest cruisers would probably serve first in the Mediterranean or with fleet and carrier escorts. Commerce raiding against Japan was possible, although assigning scarce heavy units to that mission would be an operational choice rather than their automatic role.
