Australia suffers from a strategic deficit by only having one large ship drydock.
The location of the building yards is a seperate matter but we are constrained as a maritime nation, not just naval, by not having a large ship facility in the west which could be utilised in the same way as the Captain Cook dry dock at FBE.
Graving Dock continues to serve the nation at 75
The RAN is growing in both numbers and tonnage.
Since the closures of Cockatoo Island in Sydney which had two dry docks, one capable of docking a Majestic class light carrier, and a large building slipway, the closure of the large Cairncross dry dock on the Brisbane River (medium cruise ship capable), the State Dockyard in Newcastle and the loss of Williamstown, we are in poorer shape to react to marine incidents involving large naval and civilian ships.
Both Osborne and Henderson can handle ships up to around 12000 tonnes displacement this creates a ridiculous situation where anything larger must transit to the eastern seaboard to carry out either routine or emergency dockings.
It would be a sensible investment to build (drydock) or buy (floating dock) and give the West a much needed strategic asset.
I won’t post here but if you search for large dockyards online the number of them in ROK, Japan and China is gobsmacking, makes us look like the Hobbit Shire.
