Imperial dockyards and Royal Navy strategy

What would serious 1930s naval infrastructure in Australia, Canada, and India look like, and how would it affect Royal Navy strategy?

The answer imagines multiple major yards in each region, able to build cruisers or light fleet carriers and repair larger warships, giving the Royal Navy more construction and repair options.

A serious imperial shipbuilding base would require multiple dockyards in Canada, India, and Australia, each able to build up to cruiser or light fleet carrier size. Damaged carriers and battleships could then be repaired closer to theater, while wartime orders could be spread across many more major yards. The arrangement links naval logistics, imperial infrastructure, and fleet availability.
