Certainly the problem was the age of the ships; but these suggestions are off the mark. In 1993/4 when we did the procurement the assessment team contained (and, if memory serves, was led by) one of the most competent marine engineers ever to wear our uniform. However, they were only given limited access to the ships while they were in USN service; it was these ships or nothing. And we had to make a quick decision if we wanted them. A year or so before we had had our proposals for a specially built Training and Helicopter Support Ship killed. We knew they weren't in the greatest of nicks, and, although we didn't understand the full ramifications, we accepted that and the acquisition price reflected that. Get the files out of Queanbeyan and have a look at where we were then.

the bottom line is that we went ahead and procured vessels that were known to be busted, but didn't make the effort to establish how busted they actually were.
I don't subscribe to an excuse that we had to buy within a timeframe - the US would have delayed - and if they were not prepared to allow proper assessment (and we should have hired independants to review internal engineering findings) then we should have walked. as it was the problems of rust and structural weakness were well known in other vessels of the class that were employed elsewhere. It wasn't rocket science to expect that bill and ben would in all probability be suffering from the same cancerous malaise found in sister vessels.
all these decision results flow down the line, in this case it flowed down to govt who then decided that we would not get caught again and rejected a series of other ex USN assets which were very clean and really would have been capability enablers... It affected Govts relationship with Navy and ultimately the other services as they were branded indolent by association. Nobody in the executive cares whether it was fair, justified etc or whatever. It has impacted on how DOFD passes advice to the NSC etc....
Unfort what we have now are a string of Govts who have made us buy major capabilities via intervention - and we now have major assets which were rejected by the users and the engineers but didn't tick the govts boxes for various idealogical reasons - not capability reasons.
Tigers, MRH-90's, LHA, AWD, a string of army programs etc...; all polluted by decisions that weren't focused on getting the best asset that was identified by those who wanted the capability that was actually required.
