The informed , and for once not inflammable, discussion over teh last week has pointed out the fact that any large scale construction in Adleide is likely to be a long way away.
That doesn't stop the RAN training tho' - in 4 or 5 years they could have a decent cadre of trained crews that could man a rental boat (I suggest the "Hertz" class) or co-crew a US or RN boat operating near Australia.
