Why Australia kept its County-class cruisers

Why retain County-class heavy cruisers instead of buying new light cruisers?

Missile uncertainty favoured waiting, and the Counties already offered large hulls and 8-inch guns; the available light-cruiser alternatives were judged less suitable.

Buying new gun cruisers could leave Australia needing to rebuild them when missiles arrived. Keeping the Counties postpones that commitment while retaining large hulls and 8-inch guns. American light cruisers are described as unwanted, while the British alternatives associated with the later Tiger programme are considered too small. Continued service of the existing ships is therefore presented as a temporary choice while future requirements become clearer.
