Imperial dry docks for Hood, G3, and N3-size ships

Where in Australia, British Malaya, and British India were the large docks planned, and when was construction expected to begin?

Broadly in the 1920s, at Singapore and Bombay, with Kolkata and an expanded island facility in Sydney recalled less confidently.

The proposed construction is placed broadly in the 1920s. Singapore is named for Malaya and Bombay for India, while Kolkata is suggested tentatively as a second Indian site. The Australian proposal is recalled less confidently as an expansion of an island facility in Sydney. Several ideas were being considered to spread support for large capital ships across the empire.
