Why Australia ended the naval rum ration early

Why did the Royal Australian Navy end the rum ration in 1925, and did that improve performance compared with the Royal Navy?

Cost cutting and American prohibition influence are the proposed reasons, without an improvement over the Royal Navy being credited to ending the ration.

Australia ended the issue decades before the Royal Navy, amid pressure to reduce costs and changing views about alcohol at work. The explanation offered also emphasizes Australia's cultural position between Britain and the United States during the American prohibition era. Britain regarded full prohibition as politically impossible, while Australian authorities were more willing to test the reform first inside the navy. No performance improvement over the Royal Navy is credited to ending the ration.
