If Australian ships were excluded from Royal Navy treaty tonnage, would Australia build F3 battlecruisers?
Short answerThe answer depends on Australia's separate treaty allowance, but Britain would probably first transfer existing 13.5-inch capital ships before Australia considered new F3s or other designs.
NotesFrance- or Italy-sized allowances would create very different options from a smaller quota, and excluding Canada, India, New Zealand, and South Africa would multiply the issue. Older British ships such as Tiger or Lion would provide immediate, low-cost starting fleets while the Dominions developed infrastructure and requirements.
